A man was stabbed and another assaulted in a fight at a Leamington bar on the weekend.

The OPP said three men were involved in the altercation early Saturday morning at Mezza's on Talbot Street.

"One victim was stabbed once in the abdomen. He was treated in hospital and released and another victim was physically assaulted," said OPP Sgt. Rick Tonial. "The suspect is unknown to them. They do not know who assaulted them and the reasons unknown what provoked this assault."

At this time, police have no description of the suspect, who fled the scene.
