Scotland Yard, Britain's largest police force, has introduced a smartphone app that lets London residents identify wanted suspects, according to an article from The Associated Press. 

The new "Facewatch" application has been loaded with nearly 5,000 pictures of suspects wanted in connection with low-level crime or the summer riots which hit London last year. 

Users of the app just enter their postal code and are served with photos of wanted people in their area, the article says. The residents can flip through the photos and send in a name if they know the suspect. 

The app is the latest addition to international law enforcement's arsenal of crime-fighting programs, which includes the U.S. Homeland Security's reporting tool to an app that reads suspects their rights in Spanish, the article says.
