Federal authorities have conducted a sweep through more than 100 US cities and recovered 168 children from child sex trafficking, the FBI says.
About 281 pimps were also arrested in Operation Cross-Country, a week-long enforcement that Federal Bureau of Investigation director James Comey said can help "end the cycle of victimisation" of US youth.
Denver was the FBI division with the most recovered victims, with 18, followed by Cleveland, Ohio (16), Chicago (13) and Atlanta (11).
Assistant Attorney General Leslie Caldwell said sex traffickers "create a living nightmare for their adolescent victims" who are targeted and sold for sex in the US.
"They use fear, and force, and treat children as commodities of sex to be sold again and again," Caldwell said in a statement on Monday.
