There were no clear winners, and police arrested all four.
Sandusky residents Morielle Watson, 31; Misty Artschwager, 33; Angela Fox, 30; and Siron Mills, 35; were charged with disorderly conduct intoxicated.
A bartender waved officers down at about 2:30 a.m. and told them two women were inside the bar fighting, a Sandusky police report said.
"I entered the bar and observed two females on the floor in the stock room," the report said. "Also, I observed several other males standing over top of them yelling and shoving each other."
Police yelled at the tangled mess of people, but nobody would listen. When one officer pulled out a Taser, the blows stopped.
"The two females stopped fighting and then stood up and began screaming at each other," the report said. "The two females were separated and spoken with."
Fox was bleeding from the mouth and she had several broken fingernails. Her speech was so slurred officers couldn't get "any useful information" out of her, the report said.
Police shifted their focus to the barroom, noticing several overturned tables and chairs. Witnesses said Fox had been on a rampage all night, and the fight ignited when Artschwager asked Fox "why she was being so mean," the report said. "(Fox) punched (Artschwager) in the face and (Artschwager) fell to the floor. While (the two men) were attempting to break it up, the two males began to fight each other."
Police issued citations to all four before released them to sober people.
