LIVERPOOL, England, May 27, (AP): British police were holding a 53-year-old man on Tuesday over a collision that turned a joyous soccer celebration in Liverpool to tragedy and sent more than two dozen people to hospitals, four of them in very serious condition. Police said they are not treating the incident as terrorism and are not looking for other suspects.

Detectives were working to piece together how a minivan plowed into crowds packing a narrow street, just after the players of Liverpool Football Club celebrated the Premier League championship with an open-topped bus parade. Water Street, near the River Mersey in the heart of the city, was cordoned off by police tape, and a blue tent had been erected on the road strewn with cans and bottles.

Liverpool City Metro Mayor Steve Rotheram said four of the injured were "very, very ill in hospital.” The North West Ambulance Service said a total of 47 people were injured, of whom 27 were taken to local hospitals, while 20 were treated at the scene of the crash for minor injuries. There were no reported deaths. Four of the injured are children, said ambulance service spokesman Dave Kitchin.

Hundreds of thousands of Liverpudlians crammed the streets of the port city in northwest England on Monday to celebrate the team winning England’s Premier League this season for a record-tying 20th top-flight title. As the parade was wrapping up, a minivan turned onto the parade route and plowed into the sea of fans wrapped in their red Liverpool scarves, jerseys and other memorabilia.

A video on social media showed the van strike a man, tossing him in the air, before veering into a larger crowd, where it plowed a path through the group and pushed bodies along the street before coming to a stop. "It was extremely fast,” said Harry Rashid, who was with his wife and two young daughters as the minivan passed by them. "Initially, we just heard the pop, pop, pop of people just being knocked off the bonnet of a car.”

Rashid said the crowd charged the halted 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.” Police identified the suspect as a white local man, in a possible decision to prevent misinformation from flooding social media.
