Three off-road bikers were spotted by police riding dangerously through Bradley Stoke, going around a roundabout the wrong way and mounting a pavement.
The three motorcyclists were seen first on the A38, between the M5 junction and the Aztec West roundabout yesterday (July 12) just before 1.30pm.
They then went at speed down Bradley Stoke Way before going around a roundabout the wrong way and mounting the pavement, putting pedestrians at risk.
They were last seen near the Willow Brook Shopping Centre.
When police located one of the bikes in Savages Wood in Bradley Stoke, a white man with a black hooded top and a black bandana covering his face rode the bike at a police car before heading toward Little Stoke.
Police have today put out an appeal to identify the riders. Officers are asking people with dash cam footage of the bikes to get in contact.
