Landslide in Shenzhen

A landslide buried 33 buildings at the Hengtaiyu industrial park in Shenzhen City on Dec 20, leaving seven people dead and 75 missing.

It was later proved to be a work safety incident-- the result of the collapse of waste construction material used for landfill --rather than a geological disaster.

The local government apologized to victims and 12 people who were involved are being detained. 52-year-old Xu Yuan'an, chief official who approved the waste dump site, fell to his death.

The Supreme People's Procuratorate announced it would investigate the case for suspected malpractice crimes while the search is still on.
