A man, who had earlier suffered a heart attack, died at the scene but it was not clear if his death was connected to the van attack.
At least one person is dead, and eight are in hospital after a van slammed into crowds of pedestrians in Finsbury Park, north London, just after midnight on Monday morning local time. "They were all leaving the mosque when they got hit".
"He was sitting and holding him like that, people kept holding him", Ali said.
When he woke at about 1 a.m.to the sound of a helicopter circling overhead, Hornak said, his first thought was another terrorist attack. "All of Us." The message comes the morning after a auto plowed through a nearby crowd of Muslim worshipers gathered outside a mosque just after midnight on Monday, killing one and injuring 10 more.
"An attack on a mosque, an attack on a synagogue, an attack on a church is actually an attack on all of us".
After being seized, the man said he had wanted to kill "many Muslim people", one witness told journalists.
"People were shouting this is an act of terrorism, even though he's white", another witness, Hillary Briffa, said, referring to the man taken away be police.
He has also spoken to London Mayor Sadiq Khan and said it was important to make sure the response was "sufficient and co-ordinated" and to provide "reassurance" to the community.
At a press conference later Monday, Mahmoud credited "other brothers" for assisting in protecting the man from angry onlookers until police arrived.
Police said the driver was arrested on suspicion of the commission, preparation or instigation of terrorism, including murder and attempted murder.

Labour leader Jeremy Corbyn has described the attack on a group of worshippers near a mosque in his own constituency as "terror on the streets".
"We all have harmony in this area, and these people try to divide us, but we tell them that we will not let you do that".

Police have not yet determined whether the fatality was a result of the van attack.

"We couldn't go back to bed the whole night, it was too traumatizing", Ibtisasm said.
Earlier this month, three men drove a van into pedestrians on London Bridge, before attacking people with knives at the nearby Borough Market area.
