But Georgia law allows the governor to convene a panel of two sheriffs and the state attorney general to investigate the allegations and recommend whether he should be suspended.
In addition, the Georgia Peace Officer Standards and Training Council can suspend or revoke an officer's certification if it finds he engaged in unprofessional conduct. Certification from the council is required for sheriffs to hold office.
The council has opened an investigation of Mann but will wait to make a decision on the allegations until the criminal charges are resolved, said spokesman Ryan Powell.
Mann faces two misdemeanors, for indecency and obstruction after he ran from an Atlanta police officer who confronted him Saturday night.
Mann, an attorney, was first elected sheriff in a special election in 2014.
He was previously the chief deputy under Sheriff Thomas Brown since 2001.
Before Brown, every sheriff elected to a full term in DeKalb since 1965 had faced criminal charges.
