A Didi Chuxing driver has been killed by a passenger during a midnight trip in southern China, police said, in the third murder case involving the ride-hailing firm in the past six months. The victim, surnamed Zhou, was robbed of over 2,000 yuan (about US$290) before being murdered and his body thrown under a bridge in Guizhou province last week, the state-run Guiyang Evening News reported on Wednesday. It quoted local police as saying that the passenger, a 23-year-old man surnamed Sun, had threatened Zhou with a knife and demanded cash during the trip in Guiyang, the provincial capital, on Monday last week. The 43-year-old driver called several of his relatives to borrow money during the process, but none of them realised he was being robbed, the report stated.
