Attleboro police are investigating two robberies that happened about 90 minutes apart.

Two men held up the Dodgeville Country Store on South Main Street at about 8 p.m. Tuesday.

One man showed a gun and demanded cash, while the other acted as a lookout. They fled on foot, and a K-9 search of the area turned up nothing.

Police said they are reviewing surveillance video and pursuing several leads.

The second robbery happened at about 9:30 p.m. at a Shell station on South Avenue about 2 miles away.

A surveillance photo shows a man handing over a note, demanding cash. He's thought to be in his 50s and about 5 feet 6 inches tall.

Police said they do not think the two robberies are related.

Attleboro police said anyone with information about either robbery should call city detectives.
