Authorities in Calhoun County are looking for a man who robbed a gas station early Tuesday morning.

The Marshall Police Department says that a man entered the Shell Station in the 300 block of E. Michigan Ave. around 1:30am Tuesday, and demanded money from the cashier. The man brandished a weapon, and left on foot with an undisclosed amount of cash.
