An Uber driver cleared of launching a Samurai sword attack on police outside Buckingham Palace went on to plan another attack on tourists in London, a court heard today.

Mohiussunnath Chowdhury, of Luton, Bedfordshire, allegedly boasted to undercover police how he had deceived a jury into finding him not guilty of the attack.

The 28-year-old was 'motivated by dreams of martyrdom for the cause of Islam, and inspired by preachers of hate', a jury at Woolwich Crown Court was told.

Duncan Atkinson QC, prosecuting, said Chowdbury was 'keen to take part in an attack on a high profile and very public target in the UK.'

The targets mentioned included Madame Tussauds in London, the Gay Pride parade, and an attack on tourists on a London open-top tour bus, the jury was told.

'The object was to unleash death and suffering on non-Muslim members of the public who happened to be present, using a firearm, sword and even a van as part of an attack,' the prosecutor said.

Chowdhury told undercover officers that he had indeed been trying to carry out a terrorist attack in 2017 and that he had 'deceived' the earlier jury that acquitted him of it, the court was told.

Chowdhury is accused of accused of preparing acts of terrorism and his sister Sneha Chowdhury, 25, is accused of failing to disclose information.

His sister had 'better reason than anyone to understand what her brother was thinking, and wanting to achieve,' Mr Atkinson said.

Chowdhury 'played the game' by shaving off his beard for trial Mohiussunnath Chowdhury had a big beard and looked unkempt at the time of his first trial, the court heard today. He allegedly told undercover officers that a fellow inmate gave him the advice to 'play the game' and shave his beard off. On the day of his planned 'suicide' in August 2017, Chowdhury changed his WhatsApp profile picture to a green bird, said to be a reference to martyrdom. He also wrote his sister a note which read: 'The Queen and her soldiers will all be in the hellfire they go to war with Muslims around the world and kill them without any mercy.' After his acquittal, Chowdhury told undercover officers that he had initially gone to Windsor Castle, because his intention was to kill a soldier but when he got there, he could not see any soldiers so he drove to Buckingham Palace. He said that on the way to commit the attack he had listened to and found inspiration from the lectures of the al-Qaeda preacher, Anwar Al Awlaki. During the conversation in March last year, he told the officers, that when he got to the Palace, the only soldiers he could see were too far away behind a gate to reach, so he began to manoeuvre his vehicle to attract the attention of police in a nearby van. Woolwich Crown Court was told that an officer managed to get the passenger door open and stop him from swinging or stabbing with the weapon, but there was then a short struggle with the officers trying to get the sword from Chowdhury while he was punching them and they were punching him, as he shouted: 'Allahu Akbar' [god is great] over and over again. Chowdhury was put on trial twice for the attack, after the first jury was unable to reach a verdict. Before the second trial, on September 27 2018, drawings were found in Chowdhury's cell at Belmarsh jail, which make reference to 'paradise' and showed a terrorist shouting 'Allahu Akbar' and firing at a police officer outside 10 Downing Street. At the time of his first trial Chowdhury had a big beard and looked unkempt. But he used the word 'deceive' when he was referring to his appearance and appeared 'very proud' when he was speaking about how he had fooled the jury, the court was told. 'Despite his acquittal on December 20 2018, once he was released from custody he immediately showed that his mindset had not changed one jot,' Mr Atkinson said. The mindset has been 'entrenched since at least 2017,' Mr Atkinson added. 'It was a mindset that led him to attempt to carry out a terrorist attack, putting into practice his view that the UK government, army and police were enemies of Allah and that he would be rewarded in paradise if he became a martyr for Islam through an act of violence against those enemies.'

'Whilst she may have hoped that it was all over when he was released from prison, and that his acquittal meant that he had not meant those things, his actions and his conversations with her once he was released in late December 2018 showed quite the opposite.'

Chowdhury purchased a replica Glock gun and told undercover officers what he was planning to do and why.

'He told them of his training regime, and sought to involve them in his firearms-related training,' Mr Atkinson said.

'He told them of what he was wanting and planning to do, and sought to involve them in the carrying out of one or more terrorist attacks.'

In the lead-up to the incident outside Buckingham Palace on August 25, 2017, Chowdhury's activities over the internet and on social media made it clear that he was a supporter of Islamic extremism, and ISIS in particular, the court heard.

Chowdhury told the jury in that case that his appearance with a sword outside Buckingham Palace had been an attempt at suicide, not an attack.

However, within days of his acquittal in December 2018, Chowdhury posted a story on Instagram extolling the virtues of martyrdom for Allah and an image of the police officer who had wrestled the sword away from him outside Buckingham Palace, calling him a 'cuck'.

In January 2019, he posted a series of Islamic quotations on Instagram, including reference to paradise, adding: 'Know that paradise is under the shade of swords'.

Days later Chowdhury started enquiries into firearms training, and started 'preparations to undertake that which he had been stopped from doing in 2017, an act of terrorism,' Mr Atkinson said.

On 10 March 2019, his sister's bank account was used to purchase two Red Oak 'Bokken' 40 inch wooden training swords which were delivered to the home address.

The house had been bugged and recordings picked up Chowdhury showing his sister how to use them six days later, saying: 'Let's fight here for a little bit then you do the study. You attack first and then I attack first.

'This is how, how I would strike yeah if I was running up to a person, no someone like that yeah what I would do is I run up hold the blade like that and then I would stab it like that indeed.'

Chowdhury made a reference to PC Ian Midgley, who was injured in his initial attack, saying: 'You know that Midgley character, you remember what he said, he said in the 20 years [in the police] that was the first time yeah he felt like he fought for his life.'

And on April 2, Chowdhury told his sister: 'I need to practise decapitation techniques and it's not gonna be like you know what I mean you can't do it in the garden.'

On June 20, Chowdhury told his sister that he was giving his notice in to work, adding: 'I'm doing another attack bruv.'

His sister said that he was just having a 'down day' but Chowdhury told her: 'No I'm serious bro it's about time now.'

Chowdhury used his sister's bank account to purchase the two Red Oak 'Bokken' Training Swords on March 10, the court was told.

Chowdhury tells officers he is careful not to 'text anything naughty', court hears Chowdhury took the officers to a cafe, where he read them passages from the Koran and led a conversation about Jihad, fighting and disbelievers, jurors heard. The prosecutor said Chowdhury told the officers said he was avoiding committing terrorist offences and was careful not to 'text anything naughty' to anyone. Mr Atkinson said: 'Beyond feeling able to share these admissions to previously attempted terrorism with the officers , he was also sharing with them his underlying mindset and motivation. 'That is the need to kill and to be killed for the sake of Allah, and it is that mindset and motivation that you are entitled to conclude informed his actions at this time.' On 18 March, in a Telegram app created by one of the officers, Chowdhury shared the video The Establishment of the Islamic State Pt 6', jurors heard. The piece of ISIS propaganda, said Mr Atkinson, contains execution footage, a history of the group and jihadis marching with ISIS flags. 'The prosecution case in relation to that recording which was shared with others, is that this video glorifies and encourages terrorism. It is designed to encourage others to follow and support Islamic State,' he added. The court heard that Chowdhury shared with the officers details of his acquittal in December 2018 as well as a previous trial that resulted in a hung jury. According to the officers, Chowdhury said that while waiting for re-trial Chowdhury was told by another inmate to 'play the game' and shave off his 'unkept' beard. 'Mr Chowdhury used the word 'deceive' when he was referring to his appearance and jury. 'He appeared very proud when he was speaking about how he had deceived the jury,' said Mr Atkinson. On 31 March Chowdhury started more openly talking about plans to carry out a new terrorist attack, though at that stage he was still talking about hypotheticals, the court heard. 'He spoke of Madame Tussauds as a potential site to carry out a terrorist attack as there are no bollards there. 'He also mentioned Piccadilly Circus because of how busy and iconic it is,' said Mr Atkinson. Mr Atkinson said that that Chowdhury complained to the officers about how difficult it is to get a gun in the UK, but assured them he would be able to get hold of one. After sharing a video on the Telegram channel of ISIS throwing a gay man off a building, Chowdhury expressed an interest of carrying out a terrorist attack on the Gay Pride parade, it is said. 'Thousands of homos marching and waving their flags,' wrote Chowdhury. 'The way they march they are asking to get git by some Jihadist.' Advertisement

A recording of Chowdhury training with the wooden swords against his younger sister was played for jurors.

In the audio, he can be heard once more referring to PC Midgley as a 'cuck' and adding: 'This is how, how I would strike yeah if I was running up to a person, no someone like that yeah what I would do is I run up hold the blade like that and then I would stab it like that indeed'.

Chowdhury also used his sister's account to purchase weight lifting equipment, sharing with the undercover officers this was part of his 'training' for the attack.

The officers finally got Chowdhury to open up about the previous trial after telling him they had googled him and the sword attack came up, the court heard.

One of them could sense that Chowdhury was 'really proud' and 'really wanted to tell them all about the attack' that he did.

Chowdhury played them a video of Al Qaeda preacher Anwar Al-Awlaki and shared his view that the highest form 'martyrdom' is killing unbelievers and being willing to give your life, the court heard.

The prosecutor said Chowdhury went on to tell the officers that was the reason he was specifically looking for armed police or officers in the the 2017 attack rather than civilians.

'He continued to talk about that earlier incident im 2017, talking about standing in front of a mirror home with his sword thinking about why he was going to wear' said Mr Atkinson.

'The defendant stated that he left with the intention to 'whack' a soldier however when he arrived, he didn't find anyone.

'He said that the only soldiers at Buckingham Palace were behind the gates.'

The prosecutor said that Chowdhury went on to play them the full video of the Christchurch mosque far-right terrorist attack.

He told the officers that 27 people being shot dead wasn't 'necessarily a bad thing' as it 'raised awareness' of the 'evil' of 'kufar' (unbelievers), jurors heard.

'He said that he used to worry about the way he dressed but now he didn't really care, he stated that he was proud because he realised that the Kufar had nothing to be proud about.

'He stated that he dresses in the traditional Muslim clothing just 'to p*** the Kufar off',' added the prosecutor.

In a conversation with the undercover officers on March 17, Chowdhury told them there was a 'shortcut to everything' and the shortcut to jannah [paradise] was jihad.

'The best option is where a person sets out to kill kuffar for jihad and also has the intention of being killed in the process,' he said.

On Sunday March 31, Mikael drove the group to his flat where Chowdhury asked Mikael whether he could demonstrate how to hold someone in a choke hold and the best way to hold someone hostage.

Chowdhury allegedly said words to the effect of imagine Mikael bursting through the door with the other three as his back up and said that he had seen Prophet Mohammed in his dream.

He spoke of Madame Tussauds as a potential site to carry out a terrorist attack because there were no bollards there.

The targets mentioned included Madame Tussauds in London (file picture), the jury was told

He also mentioned Piccadilly Circus because of how busy and iconic it is, the court heard.

Chowdhury gave an example of asking a drug dealer for a '10 bag' [drugs] and then eventually being able to find someone who could supply a real gun.

On April 3, Chowdhury posted a video to this Telegram group titled 'Understanding Vehicular Jihad' and added: 'Brothers watch this.'

Three days later, he told Mikael on Telegram: 'I also think about the vehicle video a lot. It's the best option for a fighter in today's age.'

Chowdhury added: 'In prison I always wanted someone to go and run a truck through the Remembrance Day but the security is just ridiculous, all the pigs are there.

'All the Royal Family, the hypocrites like [Sajid] Javid and Sadiq Khan, all the former Prime Ministers.

Chowdhury was also said to have been targeting Gay Pride in London (pictured last July)

'You know the Remembrance Day when they all go silent for 2 minutes. Imagine all the taghut [idolators] going silent, remembering the people who fought and died for taghut and the next thing you hear is 'Takbir, Allahu Akbar' [god is great], breaking that silence lol [laughs out loud].'

He added: 'The security for other events is p*** poor like the gay parades they have. 1000's of homos marching and waving their flags. The way they march they are asking to get hit by some jihadist.'

It is alleged that between January 12 and July 3 last year, Mohiussunnath booked a firearms training course, requested and selected a firearm and researched potential attack targets and asked another person to do the same.

It is also alleged that he undertook weight and fitness training, martial arts training and purchased and trained with wooden training swords called bokkens.

Mohiussunnath, a university drop out and former Uber driver, is charged under section 5 (1)(a) of the Terrorism Act 2006.

He also allegedly disseminated a terrorist video called 'The Establishment of the Islamic State Pt 6' on March 19 last year.

A third charge accuses him of possession of an ISIS instructional manual called 'Guidelines for doing just terror operations' on July 3.

Sneha Chowdhury is accused of two charges of failing to disclose information about terrorism between January 24 and July 3 last year under section 38B (2) of the Terrorism Act 2000

It is alleged she had information which she knew or believed might be of material assistance in preventing the commission of an act of terrorism and failed to disclose the information as soon as reasonably practicable to a police officer.

The trial continues.
