Police are looking for four attackers after a victim was violently assaulted in Stevenage on Christmas Eve.

At 10.20pm on Saturday, passers-by witnessed four men punching, kicking and hitting another man with a bicycle in Faraday Road.

They then made off in the direction of Harvey Road.

One of the attackers was wearing a light-coloured jacket and dark trousers.

Following the assault, the victim was seen to walk in the direction of Telford Avenue.

Officers searched the area, both on foot and with the help of a police helicopter, but the victim could not be located.

Detective Constable Karen Dewar, from the Stevenage local crime unit, said: “Due to the nature of the assault, we believe the victim could have sustained significant injuries. We are keen to speak to him in order to establish exactly what happened and to trace those responsible.”
