The head of Immigration and Customs Enforcement (aka ICE) for South Florida has been placed on administrative leave pending a child pornography investigation, according to the Orlando Sentinel and The Miami Herald.

Anthony Mangione, a 27-year veteran of ICE, has not been charged formally with any crime, but according to the Orlando Sentinel, at least four images of child pornography have been found on his computer.

The Sentinel story, an updated version of a Monday Miami Herald article, reports that the FBI and the Broward County Sheriff’s Department have seized Mangione’s computer and are in the midst of a forensic investigation. Law enforcement was originally alerted to the downloads by AOL, Mangione’s Internet Service Provider. He received the images via email.

Mangione began his career with the U.S. Customs Service as a typist and eventually became an agent. He was promoted to head of ICE for South Florida in 2007. Mangione’s focus was largely on high-profile drug busts in a region known to be the principal corridor for cocaine smuggled into the U.S. from South America.

In his capacity as a human trafficking watchdog, he has also spoken out against child pornography in the past. The Miami Herald reports:

“Too many children are victimized by predators that target the most vulnerable among us — our children,” Mangione said in a 2009 press release announcing that a 20-year-old Palm Beach County man was sentenced to more than 12 years in prison on child porn charges.

According to the Sentinel, sources close to the case say that the images do not appear to have any possible connection to any ICE cases. Neither Mangione nor any ICE officials have commented on the investigation.
