Gallant sent out his resignation letter Wednesday night writing "It was an honor and privilege to serve the citizens of Oxford County."
This came after the county commission voted unanimously Tuesday night to file a complaint against the sheriff with the governor's office, asking that the governor remove him from office.
Gallant admitted on November 21st that he took an explicit photo of himself while inside his office and in uniform and sent it to an unidentified woman.
The commissioners complaint alleges Gallant texted multiple indecent photos to one of his male officers and his female companion. It also alleges Gallant solicited them for sex.
County officials said Gallant's chief deputy will be in charge of the department for the time being.
