LOCKPORT – Though a reward had been offered, it was good old-fashioned police work that brought in a man wanted in a city bar fight.

Cory W. Arnold, 33, of Orchard Street, was charged this week with third-degree assault for allegedly walking into the 21st Amendment Bar on Main Street at 2 a.m. Sunday and hitting a man in the back of the head. The blow knocked the Walnut Avenue man out; police found him unconscious and bleeding.

A friend of the victim said the attack was unprovoked and that the man also was hit in the head by a second man.

An anonymous city businessman had offered a $1,000 reward, but Detective Kevin Schrader consulted with state police and the state Division of Parole to help identify a suspect using security video provided by the bar. Police said Arnold was contacted and turned himself in Tuesday night.

Police Lt. Scott Seekins said a second man has been identified as being at the scene, but he will not be charged.
