A gunshot was fired through a window of a house in northeast Calgary early Wednesday morning in what police believe was a targeted attack.

The shot was fired through a side window at around 3 a.m. MT in the 100 block of Templevale Road N.E., police said.

Three people were in the house at the time — a mother, grandmother and a 15-year-old boy.

No one was injured.
