Toronto police are asking for help in identifying a man in his 30s alleged to have beaten a 42-year-old man unconscious and continued to assault him after he was knocked out.

The two men had been at a nightclub near College and Crawford streets when they got into a dispute and went outside, a media release issued Wednesday said. A Toronto police spokesman would not confirm which club it was, although the Mod Club is the only major club at that intersection.

The 42-year-old man was knocked out when he walked out of the club and police say the suspect continued to beat him after he was on the ground.
