Bollards blown over by helicopter livestreaming Chongqing marathon race injure one runner

Bollards were blown over by a helicopter flying too low while live-streaming a marathon race, injuring one runner in southern China's Chongqing City on March 31.

In the video, a helicopter is seen flying very low in the sky to broadcast the 2019 Chongqing International Marathon.

However, the bollards are suddenly blown onto the racing tracks in the path of the passing marathoners, injuring one.

After the race, the runner complained to the organizing committee. The case was being investigated.
