The Chattanooga Times Free Press reports the South Pittsburg City Commission voted Tuesday to fire Sgt. Paul West.
West arrested City Administrator Sammy Burrows on Friday and charged him with obstruction of officer rights, resisting arrest, speeding and reckless driving.
Burrows has said he was speeding and put himself in "a bad position." He told the newspaper that his arrest was due to "a little bit of an internal power struggle."
City officials declined to comment on firing West other than to say employees are "at-will," meaning they can be terminated for any reason as long as it's not discriminatory.
Before voting on the matter, the board agreed to award Burrows a five-year contract.
