TUCSON, Ariz. — Tucson Police Chief Roberto Villaseñor announced Tuesday that he is firing five officers accused of being involved in a prostitution ring. A total of 10 employees were part of a months long investigation.

During an investigation of prostitution at illegal massage parlors, the Tucson Police Department found that some of its own officers were involved. Chief Villaseñor said firing the officers was a clear choice.

"When you have officers that are engaged knowingly in criminal misconduct or are untruthful when questioned about that conduct, that strikes at the very core of our profession and our agency," Villaseñor said.

The police chief also said that he's saddened that the incident gives an image of the department that is not accurate.

Two officers resigned, allegations against two were unfounded and one is pending investigation. A criminal investigation carried out by the state's Department of Public Safety has recommended misdemeanor charges be filed against six officers. Criminal charges against the business operators are being reviewed by prosecutors.

The employees still may appeal Villaseñor's decision.
