Didi executives apologize, promise better security

Killing triggers rush for mobile app, but police question effectiveness

The founder and chief executive officer of ride-hailing company Didi Chuxing, Cheng Wei, and the company's president, Liu Qing, apologized on Tuesday on Didi's Sina Weibo account for any role it might have played in the death of a 20-year-old woman in Yueqing, Zhejiang province, who was raped and killed by one of their drivers on Friday. It was the second such killing this year.

Didi will put passenger safety at the core value in the company's growth and development, rather than sheer size and profit, the statement said, adding that more emphasis will be placed on customer service.
