Apple pulled from its App Store an app that lets Hong Kong protesters see the location of police in real time, a move that comes a day after the tech giant was attacked by Chinese state media for making the product available for download.

The California-based company said it decided to remove the app, HKmap.live, from the App Store after learning it put law enforcement and Hong Kong residents in danger. Apple said customers contacted the company about the app, and the tech firm conducted an investigation into it.
