Fifty people were treated in hospital following the incident on 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.
Seven people remain in hospital and 79 casualties have been identified after the incident involving a Ford Galaxy on Water Street shortly after 18:00 BST on Monday.
Merseyside Police said it had been given more time to question a 53-year-old man from the West Derby area, who was also detained on suspicion of dangerous driving and driving while unfit through drugs.
The force said the vehicle had followed an ambulance, which had been responding to reports of someone having a heart attack, into the road.
Police said they had now spoken to 14 more people who had been injured after reporting 65 were hurt at a news conference on Tuesday.
Officers confirmed they had been granted further time to continue questioning the suspect until Thursday.
Det Supt Rachel Wilson said: "I'm pleased to say the number of people in hospital is reducing as they continue to recover from the awful incident.
