Police say they fear someone will get hurt unless quad bikes riders stop their antisocial behaviour.
Officers say there have been a lot of reports of quad bikes being ridden in an antisocial manner in the Muxton and Donnington areas.
Yesterday one collided with a car on Donnington Wood Way, the rider fleeing the scene.
A police spokesman said: "We need your help to stop them riding in this manner before someone gets hurt."
