What do we know about the incident so far?published at 16:48 BST 29 May
Police have not provided many details since Monday evening, during which time they have continued to question a 53-year-old suspect.
His identity has not been disclosed yet, which is standard practice – UK police forces do not ordinarily name suspects until they have been charged with an offence.
Questions continue to be asked about how the car came to be driving down Water Street, which was supposed to have been closed for the Liverpool FC victory parade.
Police believe the driver may have tailgated behind an ambulance which was being allowed through a temporary roadblock to attend to a suspected heart attack.
We know the suspect is being questioned about three possible offences: attempted murder, dangerous driving and drug driving.
Although counter-terrorism police were drafted in to assist with the initial investigation, police say they do not believe there is an extremist motive.
