Most of the victims are thought to have left the Muslim Welfare House on Seven Sisters Road after Taraweeh prayers held during the holy month of Ramadan when the van mounted the pavement.
Met Police said this morning that the man who died was already receiving first aid and it is not yet known if his death was caused by attack. He has been arrested on suspicion of attempted murder, according to police.
Eight others were taken to hospital and two were treated at the scene, Basu said, adding that all of the victims were Muslim.
The van which drove into worshippers near a north London mosque belongs to a Welsh hire firm.
Chairman of the mosque at Finsbury Park Mohammed Kozbar tweeted: “Our thoughts and prayers with those who got injured and effected by this cowardly attack in Finsbury Park area, many casualties in the floor”. “When it stopped, two people came out one by one with objects in their hands”. Police said the suspect has been taken to the hospital for a mental health assessment.
Some witnesses at the scene – near Finsbury Park Station and Arsenal’s Emirates stadium – said more than one attacker may have been involved. It was a white van. Some people wanted to beat him up.
– Driver was detained by members of public at the scene before police arrived.
“From the window, I started hearing a lot of yelling and screeching, a lot of chaos outside”.
“I tried to stop him (the suspect), some people were hitting him but I said stop him and keep him until the police came”.
The attack comes at a time of political turmoil in Britain, as Prime Minister May plunges into divorce talks with the European Union weakened by the loss of her parliamentary majority in a June 8 election.
Mr Welby said: “The attack at #FinsburyPark mosque is abhorrent”.
All the three incidents claimed innocent lives, however, there was only one difference, unlike the other two the Finsbury attacker was not a Muslim in fact he attacked Muslims.
Tonbridge and Malling MP Tom Tugendhat said: “Horrific terrorist attack on mosque in London. He said the vehicle was smashing into the people getting out of the mosque, so we just ran away, all of us, and came to see what’s happening”.
“I am grateful to our emergency services, who responded quickly and have been working on the scene throughout the night”.
“During the night, ordinary British citizens were set upon while they were going about their lives, completing their night worship”, said Harun Khan, the secretary general of the Muslim Council of Britain.

“While this appears to be an attack on a particular community, like the bad attacks in Manchester, Westminster and London Bridge it is also an assault on all our shared values of tolerance, freedom and respect”, he said. His attack killed five people.
