Officers are investigating two stabbing incidents that occurred in Winnipeg early Wednesday morning.

Just after midnight, police were dispatched to the Winnipeg Convention Centre after reports that a man had been stabbed.

The 20-year-old victim was working security at the DJ Tiesto event and was stabbed while breaking up a fight between several people. The victim was taken to hospital in unstable condition, but police say he has since been upgraded to stable.

Police say the fight broke out between several males, following an argument between two females. While police were approaching a man believed to be involved in the fight, an officer was assaulted to the upper body.

A 26-year-old man has been arrested for assaulting a peace officer and possession of a controlled drug or substance. He has been released from custody and is set to appear in court at a later date.

No arrests have been made in connection to the stabbing incident.

Officers were also called to a hotel in the 800 block of Main Street around 2:30 a.m. Wednesday. A 34-year-old man suffering from stab wounds was taken to hospital in unstable condition. He has since been upgraded to stable condition. Police say those involved in this incident are not cooperating with the investigating officers. No arrests have been made.

A third incident, which police are describing as an assault with a weapon, took place in the 300 block of Elgin Avenue around 10:20 p.m. Tuesday.

Officers were dispatched to a residence to check on the well-being of the male and female occupants. Police have learned that two unknown men knocked at the door and entered the suite after the door was opened residents inside who thought they knew the men outside. The two men assaulted the residents and the male was stabbed, say police.

A 38-year-old man was taken to hospital in unstable condition, but was later upgraded to stable condition. A 33-year-old woman was also taken to hospital in stable condition.
