Police have released two photos of suspects in their appeal for witnesses to an assault on two men who were attacked in Albion Street, Lewes, on Saturday (October 12).
The attack happened at 8.30pm after they asked a group of men to stop urinating in a public place.
One victim banged his head on the ground after being punched in the face and the other suffered a cut to his right hand, a graze to his chin and swelling and redness to his face and chest due to being punched.
Neither required medical help at the time.
The suspect is described as a white man, aged 20 to 25, 5ft 10in tall, of medium build, with short, dark hair cropped at the sides.
He was wearing a dark, short-sleeved polo shirt and blue jeans.
Police said they believed the suspect and two friends were travelling supporters of Sutton Utd Football Club, who were playing at Lewes Football Club on Saturday afternoon. The police statement said it was thought they were drinking in Lewes after the game.
Police are appealing to anyone who saw them around the town, possibly in licensed premises.
PC Paul Kelly said: “This was a mindless, violent act by the suspect which has shocked the victims and their family.
“The escalation from being asked to stop urinating to carrying out the assaults is shocking.”
Anyone who witnessed the incident is asked to call 101 quoting serial 1428 of 13/10.
