An officer involved in the controversial raid at a Midtown gay bar in 2009 has retired, Atlanta police spokesman Curtis Davenport confirmed Thursday.

Debra Williams, who oversaw one of the units that raided the Atlanta Eagle bar, was demoted to lieutenant last week. Her retirement was effective Wednesday, Davenport said.

The APD said in a statement: "Maj. Debra Williams has decided to retire from the Atlanta Police Department after 27 years of service. We thank her for her service and wish her well."

In an investigative report released last week, 10 Atlanta police officers were accused of lying about the events surrounding the raid. Since the findings were announced, there has been one demotion and seven other officers have been placed on administrative duty pending a disciplinary review. Two others were fired earlier.

The raid was conducted based on reports that men were engaging in sex at the bar while others watched.

Eight people were arrested, but the charges were either dropped or dismissed.

A lawsuit led to a $1 million settlement in the case.
