- Abdullah Hassan is fourth previously unidentified jihadi seen in videos
- Hassan, from Woolwich, south-east London, one of 20 men linked to drug gang believed to have travelled abroad for Jihad
- Was seen in videos with Choukri Ellekhlifi, Fatlum Shalaku and Muhammad Mehdi Hassan
- In another video, he was seen firing bullets at shooting range in Raqqa, Syria
A terrorist who posed with an AK-47 and vowed to 'wed' bullets with the 'Americans and British' in a chilling video shot on a Samsung phone which was shared by four British Jihadis in Syria has been named as one of the 'Woolwich Boys' drug gang.
In May, footage from the Samsung Galaxy smartphone revealed a chilling insight into the lives of four men - all now dead - as they travelled to the Raqqa in Syria in 2013, the former 'capital' of ISIS.
Three of the men had already been identified - British Choukri Ellekhlifi, 22, Fatlum Shalaku, 20, and Muhammad Mehdi Hassan, 19 - and the fourth man has now been identified as Abdullah Hassan, one of the 20 men linked to the notorious 'Woolwich Boys' drug gang who are believed to have travelled abroad for Jihad, the Sunday Times revealed.
The four were suspected to have owned the Samsung smartphone on which Hassan - previously unidentified - had vowed in one video: 'These bullets will be wedded with your bodies, Americans, British, French … we are here. Allah will give us victory'
In another, the four filmed each other jumping into an abandoned swimming pool in a luxury property before narrating their own Sir David Attenborough-style documentary on the Syrian wildlife they encountered.
The footage found on the phone had been downloaded to a hard drive and was later found by anti-Isis forces in eastern Syria.
Hassan was also seen in another video firing bullets at a makeshift shooting range near Raqqa.
However, despite Hassan's appearance as a hardened, merciless terrrorist in the video, the hatred on display is hard to identify with those who remember him growing up in Woolwich, south-east London.
Although it is not clear if Hassan was born in Britain or arrived with members of his family as refugees from Somalia, his Facebook profile shows his love for British TV.
He lists comedy programmes including Only Fools and Horses and Never Mind the Buzzcocks among his favourites.
One photo taken on the Milne estate in Woolwich in 2013 show Hassan smiling in a blue denim shirt; another shows him posing in a Converse t-shirt and sunglasses.
Sources told the Sunday Times that it was around this time that Hassan got involved with the Woolwich Boys, a gang heavily involved in county lines drug dealing.
Michael Adebowale, one of the men who killed fusilier Lee Rigby near Woolwich's army barracks in 2013, has also been linked with the same gang.
It is thought to have boasted around 300 members and associates and is known to have been a target for Islamist hate preachers who wanted to make converts out of vulnerable criminals.
One reformed former gangster said he knew of 16 men who went to fight in war zones in the cause of 'jihad' - he added that all were now dead.
According to ConnectFutures, which aims to turn young people away from extremism, police believe as many as 20 people from the Woolwich area may have travelled to fight in Syria.
Hassan is believed to have left for the Middle East in 2015 - he changed his Facebook profile picture in February of that year to one of him wearing Islamic robes, while his cover photo depicted a mosque in Mosul, Isis's main stronghold at the time.
Hassan is thought to have been killed before the end of the year.
One man at a barber shop in Woolwich who knew Hassan told the Sunday Times: 'We heard that he died not long after arriving in Syria.
'It's still a shock. He seemed a nice guy; very quiet and under the radar — not the type of person who would do something like this.'
Choukri Ellekhlifi was the first to use the phone in 2013 after leaving his home near the A40 flyover in West London to join 14 other men, known as the 'Westway warriors', who had left for Syria from that area.
Ellekhlifi attended the same school as Mohammed Emwazi, better known as Jihadi John, a 'Westway warrior' and leader of the so called 'Beatles' - a group that became notorious for their kidnap-and-kill crimes.
Ellekhlifi was killed fighting alongside Al Qaeda-linked extremists in Syria in 2013.
Another user of the phone was Fatlum Shalaku, 20, from Ladbroke grove, who blew himself up in ISIS's successful assault on Ramadi, Iraq, in 2015.
Tech geek Muhammad Mehdi Hassan, 20, a former private school pupil from Portsmouth is also believed to have used the phone, using his tech knowledge to offer online tips to new recruits planning to join jihad in Syria.
Hassan left Britain for Syria age 19 despite an offer at Surrey University to study international politics.
He was nicknamed 'Coco Pops jihadist' by The Sunday Times after his mother said he liked the cereal.
Hassan, who used the alias Abu Dujana, died while fighting for Isis in 2014. He tried to escape Syria but was captured only minutes away from meeting his mother across the Turkish border.
The family confirmed Hassan had died in the Syrian Kurdish town of Kobani after a picture of his body emerged on Twitter.
