NEW YORK - Federal authorities have launched a new smartphone app that enlists the public's help to catch child predators.

U.S. Immigration and Customs Enforcement officers hope the first-of-its-kind app will spread information quickly, leading to more tips and more suspects in custody.

Child exploitation investigators say users can submit a tip to the ICE tipline by talking to a live person through the app, or by submitting a web report.

All tips will be anonymous.
