What they're saying:

"The allegations in this case are deeply troubling and do not reflect the values, professionalism, or integrity of the Auburn Police Department. Our duty as officers is to ensure the safety and well-being of the public, especially children," said Caillier. "This officer has broken that trust, and this incident will be handled as promptly as possible, while still ensuring that due process is followed."

Auburn Mayor Nancy Backus also spoke with FOX 13 regarding the officer's allegations, saying, in part:

"This is not behavior, expected behavior, of our Auburn police officers. And I know they are struggling right now, because this is one of their own who has not lived up to those standards. And so my heart and my prayers go out to all of our officers and their families who are trying to deal with the reality of what they're facing today."

The details of the allegations are not yet known, and the officer is not being publicly named until he is formally charged on Monday.

The officer was booked into Pierce County Jail without bail pending the investigation.
