THE FINAL London Bridge attacker has today been revealed by terror cops as a Moroccan-Italian living in east London.

Youssef Zaghba, 22, had been arrested at Bologna Airport in March last year when he tried to travel to Syria via Turkey, Corriere Della Sera claims.

The depraved extremist along with Khuram Shazad Butt, 27, and pastry chef Rachid Redouane ploughed into pedestrians on London Bridge before hacking at revellers in Borough Market.

According to Italian website Corriere, Zaghba had an Italian mum and Moroccan dad and was born in Fez, Morocco in January 1995.

The paper said his parents had lived in the North African country before splitting up and his mum returned to Italy.

He was stopped at the airport in Bologna, where his mum lives, with just a backpack and one-way ticket to Istanbul in March 2016 and no money.

DID THEY LET ANOTHER SLIP THROUGH THE NET?

Youssef Zaghba, 22, stopped at Bologna airport from boarding to flight to Turkey in March 2016

He only had a one-way ticket to Istanbul, no luggage, a small backpack and no cash on him - raising fears he was travelling to Syria to join ISIS

Prosecutors who seized his phone found propaganda videos and images suggesting he wished to join the terror network

A complete dossier was forwarded to the MI5 in April 2016, more than a year before the attack in London Bridge, Repubblica reports

The Met's Counter-Terrorism Command say he was "not a police or MI5 subject of interest"

The paper claims Moroccan and "British authorities" were tipped off about his movements after he was charged and later cleared on international terrorism charges and placed on a "persons at risk" list.

But a statement from the Met's Counter-Terrorism Command say he was "not a police or MI5 subject of interest".

His phone was taken off him and according to Repubblica, photos showed a link to joining ISIS.

This information was sent by Italian authorities to "London", along with a complete dossier forwarded to MI5 - more than a year before the London terror attack, the paper reports.

Zaghba is the last attacker to be named following the rampage in London Bridge on Saturday night.

Ex-KFC and London Tube worker Butt was quizzed by cops over his twisted views before he was gunned down along following the depraved assault on Saturday night.

The killer and his two accomplices murdered seven people after mowing down revellers in central London before going on a rampage wearing fake bomb vests and wielding hunting knives.

The Sun had earlier revealed that the Arsenal kit-wearing ringleader of the London Bridge terror attack posed with a jihadi flag on Channel 4 documentary The Jihadis Next Door, was thrown out of a mosque and tried to radicalise kids in his local park in the years before the devastating atrocity.

Police today confirmed Butt was known to security services, including MI5.

Redouane - who also used the name Rachid Elkhdar - is believed to be a pastry chef who married a Scottish woman and had lived in Ireland.

He claimed to be Moroccan and Libyan and was not known to security services, police said.

Cops appealed for anyone with information about the men to contact police

Assistant Commissioner Mark Rowley said: “I would urge anyone with information about these men, their movements in the days and hours before the attack and the places they frequented to come forward.

“The police and our partners are doing everything we can across the country to help prevent further attacks and protect the public from harm.

“At any one time MI5 and police are conducting around 500 active investigations, involving 3,000 subjects of interest. Additionally, there are around 20,000 individuals who are former subjects of interest, whose risk remains subject to review by MI5 and its partners.

“The security and intelligence services and police have stopped 18 plots since 2013, including five since the Westminster attack two months ago.”

RED FLAGS ON HIS RISE TO TERROR ATROCITY:

Khuram Shazad Butt appeared on C4's The Jihadis Next Door unfurling a jihadi flag

He was thrown out of his mosque for ranting that voting in an election was “un-Islamic”

A friend contacted police about him due to concerns - he was quizzed but not arrested and allowed to keep his passport

He attempted to radicalise children in a nearby park

He was reported for a demonstration in Regents Park

Butt was also known as 'Abz'

Police had arrested 12 people since Saturday in connection with the attack, but all of those have now been released without charge.

Shortly after the pair were named, a copy of Butt's CV emerged on Sky News, showing the attacker's employment history.

According to the document, the extremist has been working for Transport for London (TfL) since May last year.

In his CV, Butt lists his job title as “assistant for sales and customer service office - although TfL has since revealed he left in October last year, according to BBC journalist Daniel Sandford.

He is also listed as a "coordinator" for a company called Auriga Holdings.

Jabir Bin Zayid Islamic Centre, which Butt was once kicked out of for interrupting a sermon, made a statement condemning the attacker today.

The statement reads: “We begin by reiterating and deep sense of loss and sadness at the crime these men have committed.

“Many hundreds of people pray at the Jabir Bin Zayid each week, the person that we now know to be Khuram Butt would infrequently attend this mosque.

“We did not know him well, his name was not known to us, it has been brought to our attention that some years ago after interrupting a Friday sermon he was asked to leave the mosque.

“We at Jabir Bin Zayid do not under any circumstances agree with violence targeting civilians.

“We will of course help the authorities however we can.”

A former friend of Pakistani-born married father-of-two Butt has revealed he contacted police about the terror thug’s extremist views, and claims he was radicalised after watching twisted YouTube videos.

The unnamed man said he contacted cops in Barking, East London, after the maniac killer discussed ISIS-inspired terror attacks.

He told BBC’s Asian Network that the jihadi had become brainwashed after watching clips of US hate preacher Ahmad Musa Jibril.

He said: “He used to listen to a lot of Musa Jibril. I have heard some of this stuff and it's very radical.

“I am surprised this stuff is still on YouTube and is easily accessible.

“I phoned the anti-terror hotline. I spoke to the gentleman. I told him about our conversation and why I think he was radicalised.”

After confirming Butt was allowed to keep his passport and was not arrested, he added: “I did my bit, I know a lot of other people did their bit, but the authorities did not do their bit.”

Another neighbour Erica Gasparri also said she shopped the terrorist to police in Barking when he tried to “brainwash” her children.

The Italian mum-of-three sensationally revealed that two of her kids came home from the local park and said: “Mummy I want to become a Muslim," reports the Telegraph.

She said: “He was trying to radicalise the children, he would go down to the park and talk to them about Islam.

“He also came to the houses and gave the kids money and sweets during Ramadan.”

A photographer captured a detective carrying notes yesterday which appeared to suggest a man in the investigation had been quizzed by police last year.

A YouTube video shows the extremist in Islamic dress and shades berating police outside a London mosque.

He was part of a group reported for demonstrating in Regent’s Park, central London.

A source said: “After that the word went around that he was someone to be avoided at all costs.

“With every passing day he began to look more and more like a terrorist.”

Other residents in Barking who knew the warped thug described him as a family man who held the door open for old ladies and played with local children.

But one neighbour said he constantly changed his facial appearance and “always looked different,” reports the Mail Online.

Another unnamed resident who knew him described him as a “generous” person who people would leave their children with.

Speaking with the Mail, he said: “He used to play table tennis and he was really generous with everyone's kids. People would leave their kids to play with him.

“You'd never expect anything like this from him.”

The extremist was thrown out of an East London mosque two years ago for ranting that voting in an election was “un-Islamic”.

One local said: “On Saturday he was asking one of our other neighbours where he could rent a van and how much it would cost.”

The wife of the killer, who was of Pakistani origin, had just given birth to their second child, neighbours in Barking revealed.

The couple are believed to have been living with his mum — enjoying a comfortable lifestyle boosted by state handouts.

The beast was thrown out of his local mosque in 2015 after he interrupted a sermon to shout that voting in a general election was "un-Islamic".

A source said: “He had no special friends there. He would arrive, pray and then leave.

“He seemed an uneducated person who had no knowledge of religion.”

A neighbour said: “He was into football. He would play on the park.”

He said: “He was wearing the same top yesterday. He was saying to me, 'Oh, where can I get a van from?'

"He was just asking me all the details — how much was it, and just like asking where he could get a van, basically.”

Another neighbour, Furqan Nabi, 35, said: “Abz (Butt) came from a Pakistani family but was brought up in this country from a very young age.

“He seemed like a totally normal, nice guy. I can’t believe what has happened.”

The accountant also told how the extremist asked about hiring a van.

He said: “He was a bit vague about why he wanted it.

“The reason was far more shocking than anyone could have realised.”

The family’s social housing flat was raided by counter-terror cops at 7am — one of a series of swoops in the wake of the atrocity that stunned Britain and the world.

A total of 12 people were arrested in the area and nearby.

The killer’s sister was held in East Ham.

Her husband said: “I don’t know anything. We haven’t been told what’s going on. We just want to grieve in peace.”

Half a mile from the brother’s flat, police blew in the door of an apartment and seized a mother of one aged 38 as she cradled her 18-month-old daughter.

The tearful mum was bundled into the back of an unmarked Ford Mondeo.

Her toddler was taken away in another car. A neighbour said: “Her ex-boyfriend Rashid used to live with them but moved out a few weeks ago.”

In another part of Barking — which is eight miles from the scene of Saturday night’s horror — armed cops had to talk a man out of jumping from the window of a flat they raided.

A witness said: “Five people were arrested and taken out of the house, including a woman.”

A friend of Butt, who quit his KFC job around two years ago to work on the Tube, said: “Back then he had a reputation for being a bit shady and taking drugs.

“But all that changed when he became radicalised. He began stopping his neighbours in the street and asking them if they had been saying their prayers and when they had been to the mosque.”

Deene Azak, 34, whose home is near where the killer lived, said: “I saw him two days ago and he had shaved his head. That’s how I recognised him when I saw a picture of an attacker dead at the scene at London Bridge.”
