A 53-year-old British man plowed his minivan into a crowd of Liverpool soccer fans who had been celebrating the city team's Premier League championship on Monday and was arrested, police said.
Merseyside Police said they were investigating reports that multiple pedestrians had been hit.
A video on social media appeared to show a grey minivan strike at least one pedestrian and then veer into a larger crowd of people, carving a path through the group and pushing bodies along the street like a plow before coming to a stop.

Merseyside police said they were contacted just after 6pm local time (3am Tuesday AEST) "following reports a car had been in collision with a number of pedestrians" in the city center.
"The car stopped at the scene and a male has been detained," the police added.
A spokesperson from Merseyside police told CNN "the man arrested is a 53-year-old white British man from the Liverpool area."
Harry Rashid, who was at the parade with his wife and two young daughters, said the car began ramming people about 10 feet (3 metres) away from him.
"It was extremely fast," Rashid said. "Initially, we just heard the pop, pop, pop of people just being knocked off the bonnet of a car."
Prime Minister Keir Starmer said he was being updated on the situation and thanked police for their quick response.
"The scenes in Liverpool are appalling — my thoughts are with all those injured or affected," Starmer said.
The incident followed a large celebration in the city centre, where tens of thousands of dancing, scarf-and-flag-waving fans braved wet weather to line the streets and watch Liverpool's players display the Premier League trophy atop two buses bearing the words "Ours Again."

Liverpool Football Club said it is in contact with Merseyside Police regarding the incident.
"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," it said on X.
Footage shared by Reuters news agency showed emergency services tending to people, some being carried into ambulances on stretchers.
Rashid said after the car struck the initial victims, it came to a halt and the crowd charged the vehicle and began smashing windows.
"But then he put his foot down again and just plowed through the rest of them, he just kept going," Rashid said. "It was horrible. And you could hear the bumps as he was going over the people."

Rashid said it looked deliberate and he was in shock and disbelief.
"My daughter started screaming and there were people on the ground," he said. "They were just innocent people, just fans going to enjoy the parade."
North West Ambulance Service (NWAS) said it is supporting an incident in Liverpool city center following reports of a road traffic collision.
"We are currently assessing the situation and working with other members of the emergency services. Our priority is to ensure people receive the medical help they need as quickly as possible," it said in a press release.
