Driver in Liverpool parade ramming arrested for attempted murder, believed to have been on drugs in attack

Police said the 53-year-old suspect is believed to have been on drugs

The suspect accused of ramming a car into a crowd in Liverpool at a Premier League victory parade on Monday has been arrested for attempted murder, reckless driving and is believed to have been on drugs during the attack, officials said during a press conference on Tuesday.

Merseyside Police said on Tuesday that 65 people were injured from the attack, and 11 — all in stable condition — still remain in the hospital.

Officials said a robust traffic plan was in place for the parade, which included Water Street — where the attack occurred. But, the street was temporarily reopened for an ambulance to treat someone suffering a suspected heart attack, and the 53-year-old suspect followed the ambulance inside the crowd.
