Wiltshire Police are appealing for witnesses and information after a 24-year-old man was assaulted by up to six men in Trowbridge.

The attack happened at around 10pm on Saturday 12 January.

The victim, who was walking alone from Mortimer Street towards Newtown, needed treatment at the Royal United Hospital in Bath for a broken nose and jaw as well as grazing and temporary loss of hearing.

He dropped his mobile phone during the assault and it has not been found.

Detective Constable Tracey Mead said: “This was a vicious attack on a man who was making his way to a friend’s house when he was approached from behind and repeatedly punched in the face. The violence would appear to be unprovoked.

“I would like to hear from anyone who was in the Newtown area late on that Saturday night and who saw what happened. I would also appeal for anyone who knows the identity of any of the men involved in carrying out this attack.”

Any witnesses can call Wiltshire Police on 101 or call Crimestoppers anonymously on  0800 555 111.
