A car collided with a crowd during Liverpool FC's Premier League victory parade on Monday, injuring 27 people, including four children. Two people, one youngster and one adult, are still in serious condition. The accident happened approximately ten minutes after the team's open-top bus passed through the area, according to BBC.

Four people were trapped beneath the vehicle needing to be rescued by firefighters. Twenty others were treated at the scene before being taken to hospital.

Police arrested a 53-year-old white British man from Liverpool, believed to be the driver. The incident is not being treated as terrorism, and no other suspects are being sought.

UK Prime Minister Keir Starmer called the scenes “appalling.” Liverpool FC said it is in contact with police and offered support to those affected, BBC reported.
