Police are still questioning the driver and were granted further time in an extension on Wednesday.
Officers have until Thursday evening to question the man from West Derby.
He is in custody on suspicion of attempted murder, dangerous driving and drug driving.
The force previously said they believe the car, which drove into the crowd, was able to follow an ambulance crew attending to someone suffering a heart attack, after a road block was temporarily lifted.
Hundreds of thousands of Liverpool fans had turned out to celebrate their team’s Premier League victory when the incident unfolded on Water Street just after 6pm on Monday.

He added: “Me and my partner were flat on the roof, on the bonnet… we were just both trying to hold on for dear life with Ted next to us.
“And my partner went under the wheels of the car, of the front of the car, and it rolled over her leg, and I just bounced off to the side, but my boy and his pram got bounced totally in the opposite direction – about 15ft down the road.”
Prime Minister Sir Keir Starmer travelled to Liverpool to meet with police chiefs and the local metro mayor.
He said he was being kept informed of developments, adding: “The scenes on Monday were just awful, to see how incredible joy at an amazing achievement turned to horror in a moment.”
The Prince and Princess of Wales said they were “deeply saddened” by the incident.
