Police are looking for a man who robbed a gas station and convenience store in Sioux Falls on Sunday morning.

Officer Sam Clemens says it happened just before 9am at the Gas Stop, at 415 North Kiwanis Avenue.

Clemens says a man walked into the store and went to use the restroom. When he came out he went up to the clerk and demanded cash.

He took the cash and left the store, heading south.

Clemens says the robber was described as a light-skinned black male in his late 20s to early 30s, five-feet-seven inches tall and 160 pounds. No weapon was seen.

He was wearing a stocking cap, a dark jacket and jeans.

No weapon was seen, and the clerk, a 60-year-old woman, was not injured.
