An assault victim floored by a punch has suffered hearing loss following an attack in Durham.
Th victim, who is called Jonathan and is 24, was pushed to the ground and punched by two males whilst on a night out. The assault took place on the city's Silver Street at 9pm on Saturday, April 2.
The punch to his right ear knocked Jonathan to the ground, passers-by raised the alarm and the group of three men and one woman left the scene in the direction of North Road.
He suffered facial injuries, a snapped front tooth and hearing loss to his right ear.
Police are looking to trace all members of the group particularly the man who punched Jonathan, he is described as tall, medium build with black hair. He was wearing a light grey or white top, jeans, black and white trainers and a red coat.
The victim has been unable to work since the incident.
PC Paul Vickers, from Durham City Response, said: "This was a particularly nasty assault and there was several witnesses captured on the CCTV.
"We would like to trace the group walking towards Jonathan when he was attacked, which included two young children, as well as anyone else who witnessed the incident.
"Although Jonathan's injuries were serious they could have been a lot worse, if not life changing, and it is imperative we find the people responsible. We have conducted extensive enquiries and trawled CCTV across the city and we are satisfied the group headed towards North Road. I am now asking the public for help in identifying who these people are."
Maxine Thompson-Curl, from the campaigning charity One Punch North East, added: "One punch assaults happen far too often people need to understand the horrific consequences of a single punch.
"Another person’s life has been devastated due to a needless action. I hope this exposure helps find the perpetrator and the victim gets justice. Our campaign promotes #StopThinkandWalkaway #DontUseHandsAsWeapons."
Anyone who was in the area or recognises the suspects in the group should contact PC Paul Vickers on 101.
