Video has emerged that appears to show a man being pinned to the ground and arrested after the suspected Finsbury Park mosque terror attack.
One person was killed and ten more injured when a man driving a white van careered into a group of Muslims on the street after midnight Ramadan prayers.
The attack occurred about 12:20 a.m. when a speeding van swerved into worshippers who were giving first aid to a man outside the mosque.
The Archbishop of Canterbury has compared the incident with other recent terrorist attacks, calling it "a crime against God and against humanity".
May says the man who plowed a van into a crowd of people leaving evening prayers acted alone and that people outside the mosque apprehended him. He said although the attack seems to target a particular community like the Westminster, Manchester and London Bridge, it is an attack on people's values of freedom, respect and tolerance. "Nevertheless, we will do absolutely all we can - with our partners - to protect Londoners and our city".
The incident follows only weeks after three Islamic attackers drove a van into pedestrians onLondon Bridge and then went on a knife rampage through busy Borough Market, killing eight people.
The British prime minister, Theresa May, said the attack had "once again targeted the ordinary and the innocent going about their daily lives - this time, British Muslims as they left a mosque, having broken their fast and prayed together at this sacred time of year".
London police - already stretched by a series of tragedies including a June 14 high-rise apartment fire in which 79 people are presumed dead and a June 3 terror attack near London Bridge that killed seven people - said they are putting more officers on the street to reassure the public.
Toufik Kacimi, the chief executive of the Muslim Welfare House, said the man who was arrested had to be rescued by the imam at the centre to stop him being attacked, Sky News reported.
Labour leader and Islington North MP Jeremy Corbyn has also visited the area. In a tweet, the Muslim Council of Britain condemned the incidence and wished victims quick recovery.
But Kacimi said there was no need for the community to panic, because police and government officials have been "very, very supportive".
"It is a reminder that terrorism, extremism and hatred take many forms, and our determination to tackle them must be the same whoever is responsible".
Khalid described the driver of the van as a white man who had yelled that he wanted to "kill all Muslims".
The chairman of the Finsbury Park Mosque, Mohammed Kozbar, says the incident was a "cowardly attack" on worshippers.
Elmi Abbas, another local, told MEE he had tried to help the heart-attack victim before police and ambulance services arrived.
On March 22, a man killed five people after he drove a auto into pedestrians on Westminster Bridge in London and stabbed a policeman to death.
Manchester was also hit on May 22 when a suicide bomber killed 22 people at an Ariana Grande concert.
