A day of celebrations has turned violent in the UK after a car collided with pedestrians at Liverpool Football Club's victory parade. 

Authorities say a 53-year-old white British man has been arrested and the area has been evacuated. 

47 people were injured – 27 were taken to hospital, two with serious injuries, and 20 treated on scene. 

UK Correspondent Rod Liddle told Mike Hosking it doesn’t appear to be connected to terrorism at this stage. 

He says the motives are a complete mystery.
