Findlay police are investigating an armed robbery that happened outside of a downtown bar early Tuesday.

Police responded to Nicki’s Bar at 139 N. Main St. about 2:30 a.m. Two men told officers that as they were leaving the bar, two other men approached them in the rear parking lot. The suspects were holding handguns and demanded money. The victims gave the men cash.

One of the suspects hit one of the victims on the side of the head with his gun, knocking the man unconscious. The man refused medical treatment when EMS crews arrived.

Police said the suspects ran away toward Clinton Street following the incident. Investigators said both suspects were young white men, around 20 years old and 5 feet, 7 inches tall. They were skinny and had white T-shirts over their faces. One suspect had brown curly hair and the other had short dark-colored hair.

The robbery remains under investigation.
