ALLAN Sherrington launched an unprovoked attack on a workmate who he saw walking towards Blackburn town centre.

Blackburn magistrates heard that when Sherrington stopped his car his colleague thought he was being offered a lift.

But instead, without speaking, Sherrington punched him on the jaw, knocking him to the floor, and then began to pummel him about the face with both fists.

Sherrington, 23, of Peel Mount, Knuzden, pleaded guilty to assaulting Martin Oglesby causing him actual bodily harm. The magistrates ordered the preparation of pre-sentence reports and warned Sherrington that custody would be among the options considered.

Neil White, prosecuting, said that when interviewed by police Sherrington said there had been a long period of misconduct towards him at work. Oglesby had been picking on him verbally and trying to get him in trouble with his supervisor.
