Two men were able to get away from a Cambridge convenience store with cash, cigarettes and other merchandise.
Police were called to the Short Stop on Jamieson Parkway around 1 p.m. Saturday in response to a robbery.
Both men are described as being black, thin and likely in their early 20s.
One of them was seen wearing a red T-shirt, a black baseball cap with a red brim and logo, dark jeans, black and white shoes, and a black and white bandana over his face.
The other was wearing a black short-sleeved shirt and jeans while carrying a black backpack.
