The Alberta Serious Incident Response Team is investigating after police shot a man early Friday in southeast Calgary.

Officers were patrolling just after midnight in the area of Deerfoot Trail and 17th Avenue S.E., the Calgary Police Service said in a release.

They came across a vehicle in which a passenger pointed what the officers believed to be a handgun at them, police said.

A police helicopter, canine unit and other officers were brought in, and a traffic stop was initiated, police said.

One man fled from the vehicle, police said.

"A confrontation occurred with officers that resulted in one member discharging their service firearm," police said in their release.

The man was taken to hospital in life-threatening condition. His condition was later upgraded to life-altering, but stable.

Two others were arrested. The police officers were not injured.

No other details were released.
