Three current and one former member of the Phoenix Police Department indicted on felony theft charges pleaded not guilty Wednesday to taking money for off-duty security work that allegedly was never performed.

Phoenix police officers indicted on fraud, theft charges

The charges against former Officer George Contreras and current Officers Benjamin Swarungsymun, Steven Peck and Aaron Lentz cap a three-year state investigation into the officers' involvement in an off duty security job.

Meanwhile, KTAR Radio reports all four men were ordered by the court to submit DNA samples in the death investigation of Phoenix police Officer Sean Drenth. Contreras' attorney Cary Lackey says there's no connection between the security case and Drenth's death.

Police Chief Jack Harris says Drenth's alleged misconduct involving off-duty work would have been taken to the grand jury for consideration of charges.
