One person is dead and another was taken to hospital with serious injuries after what Calgary police say was an officer-involved shooting in the southeast community of Penbrooke.

Police said they were responding to reports of a break-in at a home on the 100 block of Penbrooke Close S.E. shortly after 11 a.m. Thursday.

The canine unit that responded was told two people — who weren't known to the homeowners — were barricaded in the home's basement, acting deputy chief Ryan Ayliffe told media Thursday afternoon.
