Carpool service suspended after woman killed

China's ride-hailing giant Didi Chuxing has suspended its carpool service after police said a driver raped and killed a female passenger. A company statement said the incident showed there were deficiencies in its processes, and so it would suspend its Hitch system for reevaluation. Authorities said the 20-year-old woman hailed the ride on Friday in the eastern city of Wenzhou. A similar incident happened just months ago. In the latest incident, police said the woman got into the taxi at 1pm local time and messaged a friend for help an hour later before losing contact. Authorities detained the 27-year-old driver named Zhong early on Saturday morning, who confessed to raping and murdering his passenger, police said. The body has been recovered and the investigation is ongoing, the statement said. Didi Chuxing said Zhong had no previous criminal record, but admitted there had been a previous complaint made against him. A previous passenger allegedly said the driver had taken them to a remote place and followed them after they left the car. "The incident shows the many deficiencies with our customer service processes," Didi's statement read, saying this was "too high a cost to pay". The company also fired the head and vice president of Hitch. Didi Chuxing is the world's largest ride-hail company by number of trips, reportedly completing more than one billion journeys in the past three years. In 2016, US taxi app Uber agreed to sell its local business to Didi after failing to make a profit.
