UPDATE (6:50 p.m.): The nationwide manhunt for a "John Doe" suspected child pornographer ended a little more than 24 hours after U.S. Immigration and Customs Enforcement's (ICE) Homeland Security Investigations (HSI) issued a public appeal for information about his identity and whereabouts.
John Doe was arrested Wednesday afternoon after a tip from the public was called in to the ICE tip line. Additional details about the arrest and the identity of John Doe are being withheld pending his initial appearance in federal court.
The criminal complaint and arrest warrant for John Doe was signed Friday in U.S. District Court for the District of Columbia. At that time, HSI had no information about the identity of John Doe, but he was believed to be located somewhere in the United States.
The victim he recorded being sexually abused is believed to be seven to nine years old.
According to the criminal complaint filed by HSI, four videos of child pornography with date stamps of April 14 and 27 were first discovered by the Danish National Police on May 3rd.
They referred the case to U.S. law enforcement for further investigation.
U.S. Immigration and Customs Enforcement’s Homeland Security Investigations (HSI) is seeking the arrest of an unidentified man for producing child pornography and the rescue of a 7 to 9-year-old victim of sexual exploitation.
