The Opa-locka Police Department in Florida told an arbitrator on Wednesday that Sgt. German Bosque, who has already been fired eight times before, should be dismissed yet again.

Department representatives told arbitrator Jeanne Wood that Bosque should be fired after leaving a city-owned AR-15 assault rifle in the care of his girlfriend’s father while out on leave last year, WFOR CBS News 4 in Miami reports. This is the sixth time that Opa-locka officials have recommended Bosque’s dismissal.

Bosque holds the distinction of being the most disciplined, fined, fired, arrested police officer in Florida, according to the television news station's report. Prior to this latest incident, Bosque had been fired eight times by three different Florida police departments. Opa-locka’s previous five attempts to fire him have failed.

He previously has been accused of busting the skull of a handcuffed man, beating children, falsifying reports, possessing marijuana, and stealing from suspects, based on the report.

Bosque's union-provided attorney Andrew Axelrad maintained his client’s innocence. “It’s allegations. Allegations are not convictions,” Axelrad said. “We have a system in place and that system is a fair system.”

“I love serving the community," Bosque said. "I love what I do for a living and I’m very proud.”

After his last slip up, the police officer signed an agreement with the city agreeing that another strike would mean dismissal. Now, officials are arguing  that leaving the AR-15 in a civilian’s hands constitutes such an incident.

Axelrad disputed that claim and said that there's no evidence the weapon had been removed from a locked car trunk where it was left. The city has said the weapon should have been secured at his home or the police station.

“Anyone can legally purchase this weapon,” his lawyer added.

The city's attorney Joe Geller countered “Not just anyone can purchase one from the Opa-locka police department.”

While an arbitrator will likely issue a ruling in the next 60-90 days, the case may not get that far. The Florida Department of Law Enforcement is expected to recommend at a decertification hearing that Bosque’s license be revoked.
