When asked to confirm what the reason was behind the investigation the department said: "We are unable to comment or confirm the nature of the investigation because it is ongoing."

"When you do internal investigations, obviously you are looking for policy misconduct," retired Phoenix police officer Andy Anderson said. "When you are looking at a criminal investigation you are looking at a violation of the law."

When asked what if could mean to an officer found to have committed some crime, Anderson said, "That would be the end of his career."
