The new trustees have fought hard to clear the mosque's name, and in 2015 opened its doors as part of a nationwide initiative to improve cross-community relations following terror attacks in Paris. London's Mayor Sadiq Mayor Khan, the first Muslim to serve in that position, urged the public to focus on shared values and urged the city to stand together in an unprecedented period in the capital's history.
He said people in the crowd put the driver under citizen's arrest.
The attack will stretch the capacity of authorities in Britain, who have faced four attacks in recent months, together with a major fire that has killed dozens.
A police forensic tent erected at Finsbury Park in north London, where one man has died, eight people taken to hospital and a person arrested after a van struck pedestrians.
"A number of passers-by, or friends, or people who had come by from the mosque, were gathering around him to help take him to his family, take him to his house", Versi told Reuters.
Imam Mohammed Mahmoud was hailed for his efforts to prevent a mob attack and calm the situation before police arrived in shielding the suspected terrorist from the fury of onlookers.
Amin said that when people seized the driver, "he was shouting: 'All Muslims, I want to kill all Muslims.' Literally, he said that".
Prime Minister Theresa May said her thoughts were with those injured in "this awful incident". "We stopped him until the police came".

Mrs May said that an early assessment by police suggested the attacker "acted alone".
The next day, May promises a crackdown on extremism in Britain and warns that assailants could be "copying one another" based on similarities with the 22 March attack at Westminster. Parents are scared to send their children to evening prayers.
She said: "It's a awful, bad shock".
The attack kills 22 people - a third of them children - and injures scores more in an attack claimed by the Islamic State group. It has not been associated with radical views for more than a decade.
A 48-year-old man, the driver of the van, was detained by members of public at the scene and then arrested by police on suspicion of attempted murder. The attacker was also killed by police.
The incident comes just over two weeks after three Islamist militants drove into pedestrians on London Bridge and stabbed people at nearby restaurants and bars, killing eight.
"People feel unsafe because after the terrorist attacks of London, Manchester, the increase of Islamophobia and hate crimes", he added.
