LONDON (TNND) — Police said that the incident of a car hitting dozens of Liverpool soccer fans celebrating the city’s Premier League championship on Monday is not being treated as an act of terrorism.

"What I can tell you is that we believe this to be an isolated incident and we are not currently looking for anyone else in relation to it," the Merseyside Police Department said. "The incident is not currently being treated as terrorism.

A 53-year-old British man from Liverpool was arrested, and police said they believe him to be the driver of the vehicle and that he acted alone.

North West Ambulance Service confirmed that 27 people, including four children, were taken to the hospital. Two of those, including one child, had serious injuries. Another 20 people were treated at the scene.

Merseyside police said they arrived on Water Street after 6 p.m. on Monday after a report of a car collision with pedestrians in the city center.

"The car stopped at the scene and a male has been detained," police said.

Police said they were trying to figure out what led to the incident and asked people not to speculate or share "distressing content online."

A video on social media appeared to show a gray minivan hit at least one pedestrian and veer into a larger crowd of people.

The team issued a statement saying its thoughts and prayers were with those affected.

Our thoughts and prayers are with those who have been affected by this serious incident. We will continue to offer our full support to the emergency services and local authorities who are dealing with this incident.

Prime Minister Keir Starmer called the scenes in Liverpool "appalling" and that his "thoughts are with all those injured or affected."

"I want to thank the police and emergency services for their swift and ongoing response to this shocking incident, Starmer wrote on social media. "I’m being kept updated on developments and ask that we give the police the space they need to investigate."

City Council leader Liam Robinson said it "cast a very dark shadow over what had been a joyous day for the city."

"I would urge people not to speculate as to the motives behind this appalling incident and to allow Merseyside Police to conduct their investigation."
