“The female had her hand in a pocket of her overcoat, alleging to possess a firearm,” RCMP said in a news release.

“The employee refused to provide the money and a struggle ensued, resulting in the suspect assaulting the employee.”

The suspect left the business in a vehicle.

RCMP later located the vehicle north of Airdrie and stopped it, taking two people into custody.

“Officers did not locate a firearm inside the vehicle or on either occupant,” a news release stated.

Mounties determined the man driving the vehicle wasn’t involved in the robbery and had no knowledge of it.

The 49-year-old woman taken into custody was charged with robbery with a firearm and assault.

She remains in police custody and is scheduled to appear in court on Wednesday.
