The 29-year-old man pulled into the Shell garage next to the Caxton Gibbet roundabout just before 4pm yesterday when a blue Vauxhall Vextra pulled across his path. The driver then pulled the man from his car and assaulted him. He then attacked the female passenger who tried to pull him from the victim. Officers are now looking for the man, in his 30s, who was wearing a tight black T-shirt, blue jeans and black trainers. The attacker also had short black hair and stubble and a tattoo on his upper arm. Pc Peter Sharp said: The victim and his passenger both sustained minor injuries and have been very shaken up by this. This is believed to be an isolated incident.
