During protests in Warsaw last weekend, one crafty activist deployed a flying drone to spy on riot police.

YouTube user latajacakamera — or “flying camera” in Polish — uploaded the amazing video that the drone effortlessly captured as it hovered over teargas-filled streets.

In another video, the unmanned aerial vehicle (UAV) floats in front of a formation of police in riot gear as they rush towards demonstrators. None of them appear to notice.

Wired editor-in-chief Chris Anderson confirmed that the flying machine was built by the Polish company Robokopter.
