Merseyside Police Assistant Chief Constable Jenny Sims told a press conference: "It is believed the driver of the Ford Galaxy car involved in this incident was able to follow an ambulance onto Water Street after the road block was temporarily lifted so that the ambulance crew could attend to a member of the public who was having a suspected heart attack.
"As with many large events, with event organisers we planned for all contingencies and this included the implementation of road closures to protect pedestrians and an armed policing presence was also in place throughout the day.
"There was no intelligence to suggest an incident of this nature would take place, and as we previously stated, the incident is not being treated as terrorism.
"An extensive investigation into the precise circumstances of the incident is ongoing and we continue to ask people not to speculate on the circumstances surrounding the incident and refrain from sharing distressing content online."
