Sergeant Peter Turk tendered his resignation from the Chattanooga Police Department effective Tuesday.
The Chattanooga Police Department opened an internal investigation of Sgt. Turk on Thursday after he was taken into custody for solicitation of prostitution. The arrest came during a joint enforcement operation between the Tennessee Bureau of Investigation and the Chattanooga Police Department's Vice Unit.
Turk was off duty and not part of the enforcement operations.
The TBI's criminal case, which is separate from CPD's Internal Affairs investigation, remains active and ongoing.
