Police are searching for a male suspect in connection with a stickup at a pharmacy near downtown Hamilton.

A masked man entered a pharmacy on John Street South at Forest Avenue just after 6 p.m. on Monday.

According to police, the suspect locked the door behind him and demanded the clerk hand over narcotics from behind the counter. Holding a canister of what the pharmacy attendant believed to be pepper spray, the assailant allegedly threatened to spray the clerk if he didn't comply with the demands.

The suspect, police say, did press the button of the canister because the clerk was moving too slowly for his liking, but nothing came out.

The attendant then showed the masked man where the narcotics were kept, and then, following the suspect's orders, got on the floor in another room.

Police say the suspect proceeded to fill a garbage bag with various narcotics and took a handful of cash from the register before running out of the store.

The suspect is described as a man in 20s or 30s, five foot five, 175 lbs., with a medium build and medium length black hair. He was last seen wearing a black t-shirt, black pants, with a black piece of cloth over his face and a black covering on his head.

The Hamilton Police Service's Break and Enter, Auto Theft and Robbery (BEAR) unit continues to investigate.
