The fatal shooting of a 33-year-old woman by police has prompted the Alberta Serious Incident Response Team (ASIRT) to investigate Thursday’s officer-involved shooting in southeast Calgary.

Officers were called to the 100 block of Penbrooke Close at about 11 a.m. for a break and enter. When they arrived, it was confirmed that unknown people were in the home.

A resident of the home told Global News no one was home at the time of the break in.

“While the tactical unit was setting up, officers could hear sounds of distress coming from inside,” Acting Deputy Chief Ryan Ayliffe said.

“Tactical unit members breached the barricaded room. A confrontation occurred at approximately 12:15 p.m. and one tactical unit member deployed an ARWEN non-lethal launcher, striking a man.”

“The tactical unit members along with other CPS (Calgary Police Service) officers responded to this call in a timely manner, taking all the necessary steps to ensure public safety and the safety of our officers was not compromised.”

Police said no officers were injured.

“Their patience and due diligence was exceptional. Significant attempts were made to peacefully resolve the situation but their duty to protect both their community and fellow officers lead to actions that stopped the threat.”
