SACO (AP) — Saco police are on the lookout for a woman who robbed a city Dunkin’ Donuts shop at gunpoint.

Police say the woman entered the store on Portland Road just after 8 p.m. Wednesday, showed a black handgun, demanded cash and told employees that two men were waiting for her in a vehicle outside.

Workers gave the woman an undisclosed amount of cash, and she left the store.

Police unsuccessfully used dogs to track the woman.

The suspect is described as about 5-feet, 2-inches tall with a thin build. She was wearing jeans and a gray pullover sweat shirt with red lettering on the front and black and white sneakers. She was also wearing latex gloves and carrying a green canvas bag.
