According to British police.

The man has been detained and there were no reports of injuries.

However, unverifiable footage on social media showed a car at the front of the station and a man appearing to start a fire before being tackled to the ground by officers.

London Metropolitan Police said the incident took place just before 7 p.m. At the Edmonton police station, which was then evacuated.

Ambulances and fire engines were deployed to the scene and police tape wrapped the station.

Local police later launched an investigation led by both local and counterterrorism officers.

The Guardian reported that the incident didn't initially appear terrorism related, but there were no further details given by the police.

London's mayor thanked Metro police on Twitter, who he said brought the situation under control and continued to investigate the incident.

The terrorism threat level in Britain was raised to severe earlier this month after attacks in France and Austria, although the government says there is no specific threat at this time.
