SMYRNA, Ga. - A Smyrna police officer has been fired following his arrest on marijuana and gun charges.

A taskforce run by the Cobb County Sheriff's Office arrested Curtis Clyde Cook on Thursday and charged him with possession of marijuana and possession of a firearm.

The Marietta Daily Journal reports that the 55-year-old officer was riding in a car that was stopped by taskforce agents because it had expired tags. During the stop, investigators said they could smell marijuana and found a bag of the drug on Cook.

Smyrna police officer Michael Smith, a department spokesman, said Police Chief Stan Hook fired Cook on Friday.

A phone listing for Cook could not be located. It was unclear whether he had an attorney.
