Moosakhan Naseri, 20, was stabbed to death in October 2017

An asylum seeker who fled Afghanistan after the Taliban murdered his family was stabbed to death in a park over a £10 drugs debt, a court heard.

Moosakhan Naseri fled to England in 2015 after his father, mother, two sisters and eight-year-old brother were murdered in a revenge attack by the Taliban.

All five were shot dead as they slept after men burst into their home in the middle of the night.

But in October last year the 20-year-old was beaten and stabbed in the heart in Plashet Park in East Ham by a gang of five men over an unpaid debt, the Old Bailey heard.

Benyamen Ghaderi, 18, Azeem Shafi, 23 and Hijrat Nazzary, 25, together with Javid Ahmadzai and a 17-year-old who cannot name, 'beat the victim senseless', it is claimed.

Passing surgeon Mohammod Uzzaman, who specialised in heart and lung surgery, ran to Moosakhan's aide.

Dr Uzzaman used a police officer's knife to cut Moosakhan open and attempted to massage his heart, but he was declared dead at the scene at 4.32pm.

Prosecutor Jonathan Rees, QC, told the Old Bailey the attack happened on October 15 last year.

He said: 'It is hard to comprehend that such a small sum should provide the motive for such a vicious attack.

'Moosakhan was the subject of a violent attack by a group of fellow Afghans. In the course of the attack he was punched and kicked, and one of his attackers fatally stabbed him, once, to the left chest.

'The post mortem examination of the body revealed that he had bled to death as a result of damage caused by the stab wound to his heart and left lung.

'It was also noted that he had suffered abrasions and bruises to the face consistent with blunt assault, such as punches and kicks, there were no defensive injuries.

'It seems that Moosa owed the sum of £10 for some drugs which he was unable to pay immediately, and it was that debt which provided the context for the violent attack on him.'

He told the court the fatal stab wound was delivered b Javid Ahmadzai, who is not on trial because he fled the country.

A group playing football nearby ran over to him as Ghaderi 'delivered a further two kicks to his head,' before running off.

Telephone and CCTV evidence enabled detectives to link all of the young men to the murder.

Ghaderi claimed it was Moosa who started it by punching Javid, adding: 'We came to stop it.

'No-one touched Moosa, I never touched Moosa, Azeem never touched Moosa; Javid just stabbed him.'

Moosakhan's family were targeted as his 43-year-old father Angul was a member of the Afghan army.

He only escaped death as he was staying with relatives in the Afghan capital Kabul.

After their deaths he sold the family home in the town of Danda Ghori in Kunduz province and began a year long journey that would end with him seeking asylum in Britain in 2015.

The youngest victim was his brother Horan. His sisters aged 12 and 15 were also killed.

After a month in the shanty town at the French port he paid a people smuggler £1400 and was brought to the UK hiding in the back of a lorry.

After reaching Britain in the summer of 2015 he immediately applied for asylum – but was rejected by the Home Office.

Friends said confusion over his age on his Afghan identity papers meant that he was not classed as a child and treated as an adult.

He had been served papers to voluntarily leave but was hoping to appeal the decision.

The seventeen-year-old claimed he had tried to save the victim, despite heading to a restaurant in Barking soon after.

Ghaderi, of no fixed address, Shafi, from Stratford, Nazzary, from Greenwich, and an unnamed 17-year-old, all deny murder.

The trial continues.
