THIS is the man being hunted by police after an off-duty officer was glassed in a Blackburn town centre pub.

Special Constable Gary Douglas, 32, suffered head injuries when he was hit over the head with a pint glass in the Sir Charles Napier pub in Blackburn.

He gave chase after the attacker was thrown out of the pub before realising he could be in danger without back-up from other officers.

Police have now released CCTV of a man they wish to speak with in connection with the attack.

They said that they initially investigated whether the attack on Mr Douglas, who works in Accrington, was related to his job but have now discounted this theory.

They now believe the assault was a completely random, unprovoked attack.

PC Patrick Greene said: "On the night of the attack, the off duty special constable was enjoying a drink and it appears this was a completely unprovoked attack.

"I appeal to anyone with information to help us identify the man responsible to come forward.

"I would particularly like to speak with the man pictured and urge him to contact the police immediately so, if necessary, he can be eliminated from our inquiries."

Mr Douglas was with his father-in-law at the time of the attack in the pub just of Barbara Castle Way.

The victim, who lives in Blackburn, suffered cuts to the back of his head and was treated at the scene by paramedics.

He said: "I was having a quiet pint at the bar when I heard a smashing noise and then I felt a pain in the back of my head.

"The lad who did this was then thrown out by the door staff where he then ran away and I instinctively gave chase for a short distance before realising the potential danger.

"After thinking about what had happened, it annoys me that this individual has attacked for no reason whatsoever and I do not wish this to happen to anyone else."

The attacker, who struck at 7.45pm on September 1, was white, with medium build and short brown hair was wearing a green jacket and jeans.
