New Jersey residents can now get a "Operation Predator" app on their smart phones, to help authorities track down and arrest child predators.

U.S. Immigration and Customs Enforcement

"This app allows people to communicate with us directly if they suspect someone is abusing a child, or if they actually see one of the people who we have on the application," says the special agent in charge of the U.S. Immigration and Customs Homeland Security Investigations in New Jersey, Andrew McLees.

He says the app "will auto-dial to a tip line, so you can report a suspected predator and there's also an online link where you can fill out information about a suspected predator, and you can remain anonymous if you want."

The app also features a rogue's gallery of wanted predators, so as people are documented as fugitives, the app is updated to include them.

"Right now, it's just iPhones," McLees said. "We are developing a platform for the Droid software, and ultimately we hope to be on every smart phone. It's a must-do for every concerned citizen, we care immensely about our children, and these predators need to be brought to justice."
