OAKLAND -- An Oakland man -- captured after a footchase on a Las Vegas street -- has been indicted on charges he used using various Web sites, including Craigslist, to prostitute two girls under the age of 18, according to the U.S. Attorney's Office.

Prosecutors said a federal grand jury in Oakland has indicted 34-year-old Marcus Sewell Aug. 10 on charges of sex trafficking of children and transporting minors in interstate commerce with the intent to engage in criminal sexual activity.

According to the U.S. Attorney's office, Sewell was arrested in Las Vegas on Thursday after a foot chase and made his initial appearance in federal court in that city.

Sewell remains in custody and is expected to be transported to Northern California soon so he can appear in federal court in Oakland.

According to the indictment, Sewell is alleged to have prostituted the two teenage girls and transported them from Northern California, Nevada and Florida for the purpose of prostituting themselves between April 2005 and June 2006.

The indictment alleges that Sewell advertised the girls as escorts on Craigslist and other Web sites.

Prosecutors said the charges against Sewell are the result of an investigation by the FBI, San Jose police, the Alameda County Sheriff's Department, the Alameda County SAFE Team, the California Department of Justice and Las Vegas police.

The maximum sentence for sex trafficking of children is life in prison and a $250,000 fine.

The maximum sentence for transporting a minor in interstate commerce with intent to engage in criminal sexual activity is 30 years in prison and a $250,000 fine.
