Police are trying to track a man in connection with a Halloween attack that left a man with permanent damage to his vision.

Sussex Police are appealing for help in finding the perpetrator of an attack on a man in his own home at a Halloween party.

A 21-year-old Brighton man was punched on the side of face by gatecrashers he had asked to leave his party in Upper Lewes Road, Brighton, on October 29 in 2011.

The following day the victim's face swelled and after visiting the Royal Sussex County Hospital it was discovered he had a broken eye socket.

It was treated and healed but the incident was not reported to the police.

Nearly a year later, the victim began to suffer problems with his vision and after seeking medical attention was diagnosed with partial retina detachment as a result of the attack.

He finally reported the incident to Sussex Police in October.

Detective Sergeant Suzy MacLintock said: "We have now located a photograph of the suspect and we are hoping the public might be able to help in identifying him.”

Anyone with information is asked to contact police on 101 quoting serial 1450 of 11/10/12.
