BOSTON (AP) — An iPhone app designed to enlist the public’s help to catch fugitive and unknown 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, officials announced Tuesday.

U.S. Immigration and Customs Enforcement’s Homeland Security Investigations introduced the “Operation Predator” app for Apple products in Sept. 2013.
