RCMP say a 26-year-old woman from the Mistawasis First Nation and two teens have been charged after an armed robbery in the Rural Municipality of Shellbrook on Saturday.

Police say four suspects entered the property in the early morning hours making off with firearms, an ATV and a truck.

Mounties say a shot was fired through the window of the residence but no injuries were reported.

The woman and two 16-year-old males were eventually arrested several hours later.

They face charges of robbery with a firearm, discharge of a firearm and break and enter.
