Twelve people face federal charges for a variety of crimes related to the sexual exploitation of children, according to a news release from U.S. Immigration and Customs Enforcement.

The charges are the result of a coordinated federal effort called "Operation Predator," which involved U.S. Immigration and Customs Enforcement, Homeland Security Investigations (HSI), the FBI and the U.S. Attorney’s Office for the Central District of California.

"If they ever refused to do that, the defendant would then threaten the victims with potential exposure of those photographs to family members.
