Former Sgt. Jon Harrison was fired from Bainbridge Public Safety Monday for reasons including “violation of oath of office and violation of any criminal law or any offense involving moral turpitude,” according to Bainbridge City Manager Chris Hobby.

In addition, the Georgia Bureau of Investigation is actively investigating Harrison at the request of the City of Bainbridge, said Steven Turner, special agent in charge of the GBI’s Thomasville, Ga., office. Turner said he could not comment on the nature of the investigation.

Per the City of Bainbridge’s personnel policy, Harrison had the right to request a hearing before the city manager within three days of the firing notice. Harrison requested a hearing Tuesday but rescinded it on Thursday morning, Hobby said.

Harrison started to work with Bainbridge Public Safety on Oct. 28, 1999. He was promoted to sergeant on May 31, 2008.

Harrison, 40, has worked part-time as an officer with the Donalsonville Police Department. Chief Jimmy Holt was unavailable for comment Thursday; a secretary said he would be out of the office until next Monday. Donalsonville City Manager Marty Shingler said he had not heard about Harrison’s firing from BPS and deferred comment to Chief Holt.
