Police say they are continuing to look for three men for a savage beating at Paddy O's, 33 Union St., in August, that left a doorman with possible permanent scars.

Police and a bar manager say that around 1:15 a.m. on Aug. 19, a man went up to the doorman and said there was somebody sick in the men's room. When the doorman entered the men's room, the man who'd summoned him held the door shut while a second man inside turned off the lights, and began smashing the doorman with a bottle and punching him in the face.

The attacker and the man holding the door then ran out - along with a third man - a BPD detective and the manager told the Boston Licensing Board.

The doorman required 17 stitches on his face and two on his arm and is looking at possibly permanent scars, the detective told the board.

Police have yet to establish a motive. The doorman said he did not know the men. The manager said they had come in maybe 90 minutes earlier, had caused no problems and were not regulars.

Police have good surveillance video of the man who lured the doorman into the men's room, but the detective said that he has yet to be able to link him to any of the credit-card receipts the bar provided him.

Bar owner Noelle Somers said that as a result of the incident, bar workers now have to go into restrooms in pairs for inspections or if summoned for a sick person.
