Several pedestrians have been injured after being hit by a van near a mosque in London.
Witnesses said the vehicle veered off the road into worshippers leaving prayers in Finsbury Park shortly after midnight.
Footage showed injured people motionless on the pavement as angry crowds surrounded a white man believed to be the driver.
A spokesperson for the Metropolitan Police said officers were called at 12.20am.
“Officers are on the scene with other emergency services,” he added. “There are a number of casualties being worked on at the scene. There has been one person arrested. Enquiries continue.”
Police did not confirm claims Muslims leaving the mosque after Tarawih prayers performed for the Islamic holy month of Ramadan.
As unconfirmed reports swirled, former EDL leader Tommy Robinson, real name Stephen Lennon, was condemned for accusing the mosque of past links with extremists.
“I genuinely hope the innocent people targeted tonight outside the mosque are ok,” he later wrote on Twitter.
It was unclear whether worshippers had been leaving the Finsbury Park Mosque or nearby Muslim Welfare House, which said the incident happened “five minutes from us”.
The London Ambulance Service said it had sent a number of resources to the scene but could not immediately be reached to confirm details of casualties.
Part of Seven Sisters Road has been closed as the operation continues.
It came weeks after three Isis supporters rammed a van into pedestrians on London Bridge before rampaging through Borough Market with knives, killing eight people before being shot dead by police.
There was no immediate suggestion the incident in Finsbury Park was terror-related.
