Miami Beach Police Sgt. Mike Muley has been relieved of duty after getting drunk during an off-duty security gig.

This isn't Muley's first brush with controversy. He was demoted for his involvement in Officer Derick Kuilan's infamous 2011 drunken ATV joyride.

According to the Miami Herald, an anonymous tipster called police around 4:30 a.m. Monday that Muley appeared drunk while working off-duty security detail at a nightclub. Though police haven't confirmed it yet, that club was reportedly Mango's Tropical Café.

A midnight shift commander responded to the scene, and apparently Muley was in such bad shape that he was taken to Mount Sinai Medical Center for treatment and alcohol testing.

Muley has now been relieved of duty.

Coincidentally, Muley had been working as Officer Kuilan's supervisor the night Kuilan ran over two people after partying with a bachelorette party at another Ocean Drive hot spot, the Clevelander, and taking the bride-to-be on an ATV joyride on the sands of South Beach.

The investigation found that he failed to check in on Kuilan and fellow officer Rolando Gutierrez when they took more than an hour and a half to respond to a 911 call. The two, in fact, were partying. Muley also allegedly showed up a half-hour late that night for his shift but lied about it on his time sheet.

Muley was originally suspended for 80 hours and demoted but fought the demotion and succeeded in keeping his rank. Kuilan lost his job and in June was convicted of reckless driving. Last Thursday he was sentenced to 18 months in prison, followed by 18 months on house arrest.
