A youth soccer coach who allegedly posed online as a modeling agent was arrested on suspicion he raped a 14-year-old girl he met through a social networking Web site, police said.

Ivan Chavez, 22, of Richmond, was arrested Tuesday on suspicion of rape and sodomy and was released from Marin County Jail after posting $100,000 bond, San Rafael police spokeswoman Margo Rohrbacher said Friday.

Chavez is a self-employed contractor who coaches a girls' soccer team at De Anza High School in Richmond and two club teams in Contra Costa County, police said.

The West Contra Costa Unified School District said it had employed Chavez for the past two years but would not renew his yearly contract. District officials said Chavez had cleared a federal criminal background check.

A call to a home phone number listed for Chavez was not returned Friday.

The San Rafael girl told police in May that she was sexually assaulted by Chavez, whom she met through the MySpace.com Web site after he claimed to be a modeling agent.

The girl said she met Chavez in person in San Rafael and he drove her to a home in Richmond, where she was supposed to sign a modeling contract but was reportedly attacked instead.

An arraignment was scheduled for Aug. 16.
