(Michigan City, IN) - Michigan City Police are trying to solve an armed robbery. It happened Sunday night at Virk’s Gas Station at 1301 Franklin Street.

Police said an unknown subject wearing a mask displayed a firearm inside the store and demanded money. After being given an undisclosed amount of cash, the subject left the area on foot, police said.

A K-9 dog was used to try and track the suspect, who was not located. Reports suggested that cash dropped by the fleeing suspect, perhaps, was found when the dog was tracking the suspect. However, police revealed only that evidence related to the robbery was discovered along the track.
