A 47-year-old suspect who was arrested at the scene of an alleged terror attack that killed one person outside a London mosque has been identified thanks to video images captured during his arrest, United Kingdom media said Monday.

The suspect, who lived in Wales and was identified as Darren Osborne, was held by a crowd who had witnessed him drive a van into a group of Muslim faithful.

Metropolitan Police Commissioner Cressida Dick said the incident was "clearly an attack on Muslims."

Security Minister Ben Wallace said the suspect was not known to the security services and was believed to have acted alone.

The van struck the faithful as they emerged from a mosque in Finsbury Park after attending evening Ramadan prayers, the BBC said after broadcasting footage of the alleged attacker being led to a police van following the incident.

The man, who lived in the Welsh capital, Cardiff, had been held down by a group of people after the crash.

Osborne, who grew up in Weston-super-Mare, Somerset, and has four children, drove into the group just after midnight outside the Muslim Welfare House that also acts as a community center.
