Fort Worth Mayor Mike Moncrief is calling for federal investigators to look into what went wrong during a bar inspection at a gay bar that landed one man in the hospital with a severe head injury, the Star-Telegram reported.

Sunday's inspection at the recently reopened Rainbow Lounge has drawn loud protests from the gay community which has called the raid “police harassment.”

The inspections, carried out jointly by the Fort Worth Police Department and the Texas Alcoholic Beverage Commission, are under internal investigation by both agencies. Police officers involved have been desked. And Police Chief Jeff Halstead has announced suspension of all joint operations between the two agencies.

But the department's initial defense of the raid – the inspection was routine, and patrons sexually groped officers – has led to wider calls for an outside investigation, and has left the police department facing a public relations nightmare.

City Councilmembers Kathleen Hicks and Joel Burns, who is openly gay, were the first to call for an outside investigation.

Moncrief joined the chorus on Friday, in a written statement he asked for federal review of the police department's final investigation to ensure that the department “has thoroughly and impartially carried out its obligation to all the citizens of Fort Worth.” And added, “I encourage the TABC to follow the same course.”
