The suit stems from a fight at Schuba's in Chicago last summer. Andy Kallas is suing the bass player and the North Side tavern. He claims he suffered serious injuries to his head, mouth and face after an unprovoked attack by Wentz. Wentz says he only punched Kallas in self-defense.
The dispute took place just after Fall Out Boy left the stage at Schuba's last June. Wentz calls it another frivolous lawsuit against a celebrity.
