A lawyer for the former police chief in Prineville says he was fired as a result of accepting an assignment in 2013 to train troops in South Korea.
The former chief, Eric Bush, is also a brigadier general with the Oregon Army National Guard. Prineville officials put him on leave in September and fired him Tuesday.
The city hasn't said why, except that it was a personnel matter not related to law enforcement.
The Bend Bulletin reports Bush filed suit against the city shortly he was dismissed. His lawyer, Roxanne Farra of Bend, says Bush welcomes the chance to get the facts of his case out to Prineville residents.
Officials of the Central Oregon city wouldn't comment on the suit.
