Federal investigators expand app designed to seek public's help in catching child predators

Federal investigators say an iPhone app designed to help catch fugitive and suspected child predators led law enforcement officials to a suspect less than 36 hours after it became available.

A year later, they are hoping to greatly expand their reach by making the app available in Android and Spanish versions.

The app allows users to receive alerts about wanted predators, to share the information through email and social media, and to pass along tips by filling out an online form or calling a tip line.

It also allows users to see news about arrests and prosecutions of child predators.

U.S. Immigration and Customs Enforcement's Homeland Security Investigations launched the initial "Operation Predator" app for Apple products in Sept. 2013. They announced the expansion Tuesday.
