"That's the vulnerability for families and their children," he said. "They really have to monitor their children's activities because on social media they can meet these people."

Nationwide, the FBI said, the operation rescued 168 children and arrested 281 pimps in 106 cities across the United States. Operation Cross Country VIII works with U.S. attorney's offices and the Department of Justice's Child Exploitation and Obscenity Section to aid federal prosecutions.
Between January 2013 and now, the Maryland Child Exploitation Task Force has rescued 49 girls from sexual exploitation, including 20 from Baltimore County, six from Baltimore and three from Anne Arundel County, the FBI said.
