PASADENA, Texas - A Pasadena police sergeant has resigned from the department while he remained under an active internal investigation, according to the Pasadena Police Department.

The resignation comes as a Pasadena city council member exclusively told KPRC 2 that the sergeant was being investigated for allegedly misusing the department's Flock Safety license plate reader camera system to track a fellow officer.

For months, KPRC 2 has been looking into allegations surrounding Sgt. Michael Palitz after receiving information about an internal investigation.
