Five men were taken into custody in Orange County, Fla., Friday on suspicion they ran a child prostitution ring out of their apartment, offering clients sex with 11 and 12-year-old girls, according to Local 6 News.

Investigators said Alfredo Perez, Miguel Herrera, Manuel Lopez-Tino and two others used two Asian sisters for sex with a variety of men.

The illegal immigrants from Guatemala allegedly sold the girls out of the Silver Oaks apartment complex in Pine Hills, Fla., according to the report.

The alleged child porn operation was busted after a tip from a neighbor led police to the girls.

"The girls are saying that they have been molested in one way or another in the course of the last couple of years," Orange County Sheriff's Lt. Matt Irwin said. "They would come over, pick the girls up and take them back to their apartment and engage in the sexual acts, pay them and take them back home."

The girls' stepfather was also arrested for allegedly molesting them, Local 6 News reported.

Neglect charges against their mother are pending an investigation, according to the report.

"I can tell you that mom and dad knew that both of these girls were sexually active with adult men," Irwin said. "Not, maybe for money. You are talking an 11-year-old who said she had sex more than 100 times with a couple of different people."

Detectives said the men admitted to the crimes during questioning, Local 6 News reported.

The girls were in Department of Children and Families custody early Saturday.

More arrests are possible in the case, police said.
