Once again, a Mac's store in Thunder Bay has been hit by a robber.
Sunday, just after 10 p.m., a man went into the store on South Syndicate Avenue with a knife.
He made off with an undisclosed amount of money.
No one was injured.
Police do have a description of the suspect.
Mac's Convenience Stores is working with Thunder Bay and District Crimestoppers in the wake of a rash of robberies in the city over the past year.
A spokesperson for Thunder Bay Police says the company is contributing money for rewards for anonymous tipsters whose information helps police track down robbers.
