A Prairie View police officer who used a stun gun on a city councilman last fall has been indicted on a misdemeanor charge of official oppression, according to authorities.

Noah Johnson, an assistant criminal district attorney with the Waller County District Attorney's Office, said Monday that Prairie View Police Officer Michael Kelley had been indicted Friday on the charge of official oppression after tasing and arresting Prairie View City Councilman Jonathan Miller in October. 

"The reason the grand jury indicted Officer Kelley was because the arrest he made was unlawful and Officer Kelley knew it was unlawful at the time he made it," Johnson said, adding that the DA's office on Monday had dropped charges against Miller. 

The indictment marks the second time in the last month that a law enforcement officer  has been criminally charged in Waller County related to their actions on the job.
