A former Fulton County deputy sheriff pleaded guilty in federal court to demanding money from security officers he assigned to work at public swimming pools, the U.S. Attorney’s Office said today.

Reginald Warren, 50, of Covington, accepted thousands of dollars in kickbacks during the summer of 2011, according to prosecutors.

While working with the Fulton County Sheriff’s Office, Warren had a contract with the City of Atlanta to run security at its public pools. He hired officers and coordinated their schedules, but soon demanded payments from at least three of them in exchange for continuing to assign them more work, authorities said.

“Those who work within the law enforcement community must maintain the public’s trust and respect,” U.S. Attorney Sally Quillian Yates said in the news release. “By entering his guilty plea, he acknowledges he violated his oath of office and betrayed those he promised to protect.”

No sentencing date was announced.
