A man dressed as American gonzo journalist Hunter S. Thompson for Halloween was stabbed in the neck with a broken beer bottle last night by three masked men who didn't like his costume.

At 3:34 a.m., police were called to College and Bathurst streets after a man was found on the ground with a stab wound to his neck.

The victim was walking east on College when he came across three men who insulted his costume, police say.

"They were making fun of his costume," said Staff Sgt. Paul Hargan.

The victim continued walking when the suspects approached him from behind and swore at him before one of the suspects, dressed as Jason from Friday the 13th, stabbed the victim in the neck with a broken beer bottle.

The suspects ran through crowds of people partying, Hargan said.

A bouncer at a nearby club tied a shirt around the victim's neck and applied pressure to the open wound. The victim was sent to a nearby hospital.

Because the suspects were masked, police don't have a description.

Police are looking for witnesses.

"It was a very busy night with people out partying so someone must have seen what happened," Hargan said.

Anyone with information should call police at 416-808-1400 or Crime Stoppers anonymously at 416-222-TIPS.
