A 20-year-old man has died of his stab wounds, following a fight that occurred between two groups late Thursday night in northeast Calgary. 

At about 11 p.m. on Thursday a group of young men were passing by the Mezzaluna Bar in the 900 block of 36th Street N.E. when they got into a fight with another group of men in the parking lot, police said.

The 20-year-old man, whose name hasn't been disclosed, was stabbed and beaten with a baseball bat.

EMS crews took the victim to hospital where he later died of his injuries. An autopsy will be conducted Friday or Saturday, police said.

Three people were detained shortly after the incident. They have been interviewed and cleared of having any involvement in the case, police said.

"We know there is a licensed premise in that area. One group came out of that licensed premise; the other group were in the parking lot," said Calgary police spokesman Kevin Brookwell. "What was said that led to that fight we haven't been able to determine yet."

No arrests have been made, and police asked witnesses with information to contact them.
