RCMP are looking for a suspect in a string of recent bank robberies in southern Saskatchewan.

On Thursday afternoon, RCMP responded to a robbery at a bank in the community of Lang.

Police say a man wearing a helmet and visor entered the bank and gave an employee a note demanding money before fleeing on foot.

Investigators believe the incident is related to three other bank robberies that occurred over the past two weeks in the communities of Grenfell, Vibank and Sedley.

In each of the robberies, the unarmed man hands over a note demanding money, then leaves the bank and walks to an unknown vehicle parked several streets away. He wore a helmet with a visor in three of the robberies and a mask during the one in Grenfell.

Anyone with information about the robberies is asked to contact RCMP or Crime Stoppers.
