A teenager was reportedly punched in the head and left with bruising after his bicycle and a car collided in Gloucestershire.
The 16-year-old boy was knocked to the ground on Ermin Street in Brockworth by the crash before the driver left his black vehicle and assaulted the boy shortly before 4.50am on Wednesday.
The driver then returned to his car, turned around and drove on Moorfield Road in the direction of the Churchdown area, leaving the boy shaken up by the incident.
He was described as being a white man, aged between 40 and 50, of a medium build, around 5ft 11ins in height, with brown hair which was balding and brown stubble on his chin.
He was wearing blue jeans and a red and grey check shirt.
It is thought he may have been driving a Vauxhall Corsa or a Nissan Micra.
Enquiries have been taking place in order to try and identify the driver and police are now appealing for any witnesses or anyone with dash-cam, CCTV or doorbell camera footage to contact them.
A number of cars are reported to have driven by at the time and police are keen to hear from anyone who was travelling in the area and may be able to assist.
Anyone with information can submit this to police online and referencing incident 92 of 16 June.
