The Colorado Attorney General says a child-trafficking ring coerced or lured at least four girls under the age of 18 into prostitution in five Colorado cities including Grand Junction.

The 70-count indictment, made public Monday, charges four people with taking the girls to locations in Denver, Boulder, Lakewood, Grand Junction and Glenwood Springs to have sex with paying customers.

They face charges including trafficking in children, pimping of a child and inducing child prostitution.

One also faces drug charges. They were arrested over the weekend.

If convicted of child trafficking, each could face up to 24 years in prison and up to a million dollars in fines.

Ten other people were indicted on charges of abetting or patronizing the operation.

All but two have been arrested. All the alleged prostitution incidents occurred last year.
