The head of an urban enforcement agency in Shenzhen, where a huge landslide left scores of people missing, has killed himself, authorities said on Monday.
Xu Yuan'an, head of the City Urban Administrative and Law Enforcement Bureau for Shenzhen's Guangming New District, jumped to his death late on Sunday, according to a post on an official police social media account.
After an investigation, police determined Xu's death was a suicide, the post said.
Only seven deaths have been confirmed from the landslide, which struck just over a week ago. But 75 people are unaccounted for after more than 30 buildings were buried.
Soil was illegally piled 100 metres high at an old quarry site and turned to mud during rain, according to the state-run Global Times.
Xu was among the officials who approved the landfill project, according to a report by the Shenzhen Special District newspaper that was later deleted.
Cynical Internet users raised the spectre of corruption having played a role. "There goes all the evidence", one commentator wrote. "Now we'll never know what really happened".
Meanwhile a report said police detained 12 people in connection with the landslide. In a brief report, the Xinhua news agency said police had taken "coercive measures" against 12 people, including "responsible people" from Shenzhen Yixianglong Investment Development, which ran the dump.
