Gunshots rang out early Sunday morning inside the Last Call, 729 N.H., although no one was hurt and no one was arrested.
Lawrence Police responded to the downtown nightclub after someone fired several shots from a .22-caliber handgun, Police Capt. Ray Urbanek said.
The shots may have been fired after a scuffle between two patrons on the dance floor, Urbanek said. The bar employee who broke up the fight heard the shots as he was escorting one of the participants out of the club.
Police recovered several shells from the scene, but not before a rush of people fleeing the club created confusion.
"It was a literal human stampede," Urbanek said.
Police have no suspects at this time.
