WASHINGTON -- The FBI says it has found 69 child prostitutes across the country during a crackdown on the sexual exploitation of children over the last three days.

Federal, state and local authorities in 40 cities also arrested 884 people, including 99 suspected pimps, on a variety of charges.

The children were found during Operation Cross Country V, a three-day roundup targeting child traffickers and pimps.

The FBI is working with the National Center for Missing and Exploited Children to identify the children. The child victims are removed from prostitution; the adults face a variety of state and local charges.
