A SWAT team was dispatched Wednesday to arrest a Beaverton police officer accused of sexually assaulting a 5-year-old child.

Christopher R. Warren, 33, who lives in Vancouver, was taken into custody at his home in the 9200 block of Northeast 14th Way, Vancouver police said. He was booked into the Clark County Jail on a rape of a child charge.

Warren was placed on paid administrative leave last month when he was arrested in Washington County on accusations that included food stamp fraud, theft of at least $1,000 from the state of Oregon.

Officer Mike Rowe, a Beaverton police spokesman, said Wednesday that Warren is still on paid leave and an internal investigation is ongoing.

Warren pleaded not guilty to unlawfully obtaining of public assistance, unlawfully obtaining food stamps, theft and unsworn falsification charges on April 30. He is scheduled to appear in Washington County Circuit Court next Tuesday.

Warren joined the Beaverton Police Department in 2004 after spending two years as a reserve officer. He was placed on paid leave in September 2009 when the Multnomah County district attorney's office investigated claims he inappropriately touched a girl when he was 17, the agency said.

The case was dropped in April 2010.

He was placed on paid leave again one month later, the police department said. At the time, Multnomah and Washington County investigators were looking into allegations that he failed to report suspected child abuse involving one of his childhood friends, according to a memo from Multnomah County prosecutors detailing the investigation.

The friend, Sugar Ray Black, was convicted in 2010 in the sexual abuse of three girls who were 14 years old or younger, court records show. He was sentenced to six years and three months in prison.

Warren was fired from the Beaverton Police Department in January 2011 and then reinstated nine months later as a desk officer, police said.

Warren allegedly applied for food stamps in Oregon after he was fired even though he was living in Vancouver. He is accused of also continuing to collect food stamps three months after he rejoined the police department.
