An internal affairs investigation has concluded that agents committed multiple violations in a raid at the Rainbow Lounge, a gay bar in Fort Worth, Texas, which left one man hospitalized with serious brain injuries.

Agent Christopher Aller and agent trainee Jason Chapman are accused of participating in the June 28 raid without their supervisor’s approval, disrupting the business during the raid and wearing improper attire in the beverage commission report obtained by The Associated Press under the Texas Open Records Act.

The investigation also found that one of the agents’ supervisors, Sgt. Terry Parsons, failed to ensure the agents submitted a report on using force during the arrest, did not take appropriate action after learning they didn’t wear proper attire during the raid and did not notifying supervisors multiple arrests had been made that night, the report states.

Aller and Chapman have been placed on desk duty pending the outcome of the investigation, and Parsons decided to retire. All three could face disciplinary action ranging from a verbal warning to job termination for numerous policy violations, but no decision has been made on any penalties, agency spokeswoman Carolyn Beck said.
