Londons Metropolitan Police reported a number of casualties early Monday whena vehicle collided with pedestrians shortly after midnight local time, in what police have called a major incident.

Authorities say one person has been arrested in the Finsbury Park area of north London, and the citys Ambulance Service said a number of resources had been sent to the scene.

Witnesses told HuffPost UK that about 10 people were injured by the vehicle, although authorities have not yet confirmed the number of casualties.

The incident occurred near the Muslim Welfare House, a community center down the road from several local mosques,according to the U.K.s Muslim Council.The mosques had been holding evening prayers for the holy month of Ramadan.

Authorities have not yet confirmed whether Mondays incident was an accident or an attack.

Cynthia Vanzella, a woman who lives near the scene, told CNN she heard the collision from her home and went to a window to see people desperately trying to make some signs to a police car.

I saw a lot of people injured, she said. They were helping on the pavement and trying to help them to get to the scene.

The gentleman went straight down this road, people were just conversing, talking, just doing what were doing. And he just came into all of us,a witness told the Press Association.

I was shocked, shocked, shocked, he added. There were bodies around me.

There was confusion and dismay among witnesses and bystanders in the aftermath of the incident. Anxious crowds gathered at police cordons surrounding the area to wait for news.

A HuffPost UK reporter witnessed police detaining a second personseveral hours after the collision. Authorities declined to comment on the reason for the arrest.

The chairman of Finsbury Park mosque, Mohammed Kozbar, described the incident as a cowardly attack and said there were many injuries.

Prime Minster Theresa May has been informed of the incident, Reuters reported.

This is a terrible incident, May said in a statement. All my thoughts are with those who have been injured, their loved ones, and the emergency services on the scene.

Opposition leader Jeremy Corbyn said he was totally shocked. My thoughts are with those and the community affected by this awful event, he said in a statement.

Mondays collision is the latest in a series of incidents in the country involving vehicles hitting pedestrians.

In March, four people were killed and dozens were injured after a man drove his car into a crowd on Westminster Bridge and then stabbed a police officer. In June, men driving a van plowed into pedestrians on London Bridge and then began stabbing people in a popular market, killing eight.

In both instances, the attackers were killed by police.
