Police are appealing for witnesses after a man was assaulted in an unprovoked attack in Lancaster.

Around 3.00am on Sunday 12th June, a 27-year-old man was waiting at a bus stop on South Road when he was approached by another man.

Without warning, the man hit the victim over the head with his arm which was in a plaster cast before getting on the same bus as the victim.

The victim attended the Royal Lancaster Infirmary the following day and was treated for a small cut to his head.

Police have released CCTV of a man they would now like to speak to and are appealing to anybody with any information to come forward.

PC Chris Smith said: “This was a completely unprovoked attack and we are determined to find the person responsible.

“If anybody has any information whatsoever about this assault then I would urge them to contact police.

“I am also keen to speak with anybody who recognises the man captured on CCTV.”

• Anybody with any information is asked to call 08451 25 35 45 or call Crimestoppers on 0800 555 111.
