Another night and another pair of robberies at Mac's Stores in the City. The first took place just after 2:30 this morning at the Balsam and River Street location, where a man entered the store brandishing a knife and got away with cash and lottery tickets. The thief drove off in a blue vehicle. The second heist occurred around 4:20 at the Mac's Store on Arthur Street West. Again, a lone male was armed with a knife, and ran off with money and lottery tickets. There were no injuries in either robberies.
