Fifty people were treated in hospital following the incident in Water Street
Police have been given extra time to question a man arrested on suspicion of attempted murder after a car ploughed into football fans during Liverpool's Premier League victory parade.
Merseyside Police said a Ford Galaxy avoided a roadblock by tailgating an ambulance that was responding to reports of a member of the public having suffered a heart attack.
The force said it had been given an extension to continue questioning a 53-year-old man from the city's West Derby area. He was also detained on suspicion of dangerous driving and driving while unfit through drugs.
Fifty people, including children, were treated in hospital following the incident in Water Street shortly after 18:00 on Monday.
Police said that seven people remain in hospital in a stable condition following the incident.
She added the incident was not being treated as terrorism.
Hundreds of thousands of jubilant Liverpool fans packed the city centre on Bank Holiday Monday and lined the 10-mile (16km) parade route as the Reds celebrated winning their second Premier League crown and 20th top-flight league title.
