Debris lay strewn over Liverpool’s Water Street on Tuesday (27 May) after a car ploughed into a crowd during Liverpool’s Premier League victory parade on Monday.
Four children were among around 50 people injured in the incident, with one youngster seriously hurt.
The “horrific incident” was not being treated as terrorism following the arrest of a 53-year-old man at the scene, Merseyside Police Assistant Chief Constable Jenny Sims said.
She urged people to refrain from sharing “distressing footage” from the incident online, but called for videos to be passed to the police.
The force said the suspect was the driver of the car, white, British and from the Liverpool area.
