A police helicopter crashed this morning at Beijing's Northeastern Miyun Reservoir, according to Xinhua.
Five crew members fell into water after the crash, and one of them has been saved with no life-threatening injuries.
The crash happened on a return voyage after finishing a search and rescue training. The training was launched after several reported cases of people being trapped in Beijing's suburbs due to frequent rainstorms this summer.
Fu Zhenghua, Beijing's Municipal Public Security Bureau Chief, arrived at the scene after the crash to direct the rescue operation. Causes for the crash are still under investigation.
