SAN FRANCISCO -- A federal jury has convicted an Oakland man on two counts of sex trafficking for recruiting a 15-year-old Reno girl to prostitute on the streets of San Francisco and Oakland in July 2011, a federal official said Friday.

Roderick Harold Bolds was earlier this week convicted of one charge of sex trafficking of children and another charge of transportation of a minor for purposes of prostitution, according to United States Attorney Melinda Haag. His age was not available late Friday.

A jury found that between July 4 and July 11, 2011, Bolds prostituted the victim, who he knew was a minor, on the streets and placed an advertisement for her services online.

The victim was arrested in San Francisco's Mission District on prostitution-related charges by San Francisco police, who turned the case over to the FBI, federal officials said.

Bolds was indicted by a federal grand jury on September 27, 2011 and has been in prison since his arrest. He will be sentenced in April in San Francisco. He faces a mandatory minimum sentence of 10 years in prison.
