Two armed men with bandanas over their faces entered the store around 4:45 a.m. and demanded money from the clerk, police said.
One suspect was wearing a black jacket, black shoes, a black bandana over his face, a black-and-white striped hoodie with a white T-shirt underneath and gray pants.
The second suspect wore a white hoodie with multi-colored stripes, long red gym pants with white stripes down each leg, red shoes and a red bandana over his face.
Police believe the robbery could be connected to three other robberies at convenience stores in the same area within a four-day period.

In each case, the robber pointed a gun at the clerk and wore dark clothing and a bandana over his face, police said.
