VANCOUVER -- A Beaverton police officer already accused of food stamp fraud was arrested by SWAT officers at his Vancouver, Wash., home in connection with the sexual assault of a 5-year-old child.

Christopher Warren, 33, was arrested Wednesday. He was booked into the Clark County Jail on an accusation of first-degree rape of a child, said Vancouver police spokeswoman Kim Kapp.

Warren was arrested about 3:20 p.m. at the home in the 9200 block of NE 14th Way by tactical officers assisting detectives from the Children's Justice Center unit.

Neighbor Ben Ruth told KGWhe was shocked and appalled by the arrest of his neighbor.

I couldn't believe this was happening, especially with Chris being affiliated with the police department, he said.

In 2009, Multnomah County investigators looked into allegations of inappropriate touching of a minor dating back to when Warren was a teen. The case was dropped when the alleged victim declined to cooperate.

A year later, Warren was accused of failing to report a crime after a friend was convicted of child sex abuse. He was fired, then reinstated.

Last month, Warren pleaded not guilty to unlawfully obtaining public assistance, unlawfully obtaining food stamps and theft.

Warren has been on paid administrative leave. Beaverton police Officer Mike Rowe said an internal investigation of Warren was ongoing.
