BOZEMAN, Mont. -

A former Gallatin County sheriff's deputy has filed a lawsuit to get his old job back.
    
The Bozeman Daily Chronicle reports (http://bit.ly/1nqr3O7) that David Johnston filed the lawsuit Wednesday in Gallatin County District Court against the sheriff's office and Sheriff Brian Gootkin.
    
Johnston contends he was wrongly fired on July 23.
    
The lawsuit says that on July 9, Johnston called Deputy Kelly Munter, his former girlfriend, for backup after finding an unlocked door at a school. The lawsuit says the two had problems and Munter left.
    
The lawsuit says a complaint was filed against Johnston and he was told to turn over his recorder and its contents for July 9 but delayed so he could make a copy.
    
The lawsuit says Johnston was fired for not immediately turning over the recorder.
