LINCOLN, Neb. (AP) — The state fire marshal has shut down a biker clubhouse in northeast Lincoln that authorities suspect has been operating as an illegal bar.

Fire authorities say the Zodiac’s Motorcycle Club clubhouse lacks a safe second exit. The two-story building once housed a gas station. A meat business is operated out of the rear of the building by the building owner, who rents Zodiac’s the main floor.

Zodiac’s does not have a liquor license. Operating an unlicensed bar is a misdemeanor that carries a $500 fine.

The Lancaster County Sheriff’s Office has been investigating a March 25 brawl at the club, but no arrests have been reported.
