Police are searching for six men believed to be involved in an attempted robbery near Yonge-Dundas Square that sent a man to hospital with a stab wound to his leg Tuesday night.

Investigators at 52 Division say the injured man in his 20s stumbled into the Pickle Barrel restaurant on Yonge Street at about 7:30 p.m. and lost consciousness. But Const. Craig Brister said the man was in stable condition Wednesday morning and that his injuries were not considered to be life-threatening.

Police say they are looking for a black male suspect, wearing a black windbreaker and allegedly carrying a large knife at the time. Five other men are believed to have been involved in the robbery, Brister said. Investigators are reviewing video footage of the scene and may release more information.

Police initially reported Wednesday they were looking for four men, but Brister said later that six people are believed to have been involved.

The victim had been wearing a chain that police say the men tried to steal from him. It's unclear whether the victim knew his attackers, as Brister said he did not believe police had been able to interview the man yet.
