A man was head butted in an unprovoked assault at a pub in Bury.

A 36-year-old man was inside the Derby Arms on Bolton Road at about 11.30pm on July 11, when another man sat next to him. He spoke to the victim before head butting him.

The victim suffered a cut above his right eye that required five stitches.

Now police have released a CCTV image of the offender, who was wearing a distinctive striped top.

Anyone with information is asked to call Bury CID on 0161 856 4647, or the independent charity Crimestoppers, anonymously, on 0800 555 111.
