Public to give police tipoffs via new app

Beijing police have launched a whistleblower app for members of the public to report tipoffs about crimes and help maintain public security.

The app went viral on Tuesday because it is named after the mysterious whistleblowers who have been repeatedly described by the police authority in the capital as "Chaoyang Qunzhong", which means "the public in Chaoyang district".

The name has been frequently cited as a source of tips for the Beijing Municipal Public Security Bureau in cracking down on major criminal cases, such as those involving drug use and trafficking, as well as prostitution.
