In Denver, 24 were arrested for prostitution, two were taken into custody for being pimps and another was arrested on an outstanding warrant.

Agents rescued 52 children in a series of raids around the country, though no children were found in the Denver area busts, according to FBI spokeswoman Kathy Wright.

"Child prostitution continues to be a significant problem in our country, as evidenced by the number of children rescued through the continued efforts of our Crimes Against Children task forces," Kevin Perkins, assistant director of the FBI's Criminal Investigative Division, said.

Officials checked out massage parlors located at 1529 Champa Street and 2060 S. Huron Street as part of the Denver investigation.

Authorities say the youngest victim was 10 years old, but didn't say where she lived.

Police from Denver, Aurora, Lakewood, Commerce City and Thornton participated in the busts with agents from the FBI, according to Wright.

The bureau and local police officials also arrested 60 pimps during the three-day enforcement effort in 36 cities.

The raids are the latest in a long-running Operation Cross Country aimed at child prostitution rings around the country.

Agents made the most arrests in Miami, where 85 people were arrested. Las Vegas and Chicago ranked second and third. Denver ranked 12th in terms of the number of people arrested.

Almost 1,600 agents and officers took part in the raids, which led to federal and state charges against a total of 691 suspects.

The investigations typically target places where minors are likely to be sold for sex, including truck stops, casinos, public streets, and Internet Web sites.

-Xioa. Yan L., 40

-Clark, Xue E., 44

-Gallegos Eric R.

-Wyatt-Childs, Terry Sue, 48

-Snoddy, Tonya, 38
