Police in southern China say a local government official has killed himself, a week after a landslide from a pileup of construction waste in his city left scores missing and presumed dead.

A statement from the Shenzhen police said the head of the Urban Management Bureau in the city's Guangming New District jumped to his death from a building Sunday.

The official was identified only by his surname, Xu. No further details were given.

In the Dec. 20 disaster, a mountain of construction waste collapsed amid heavy rains onto an industrial park in Guangming New District, killing one person and leaving 75 missing and presumed dead.

In a rare move, Shenzhen's top officials, including the city's Communist Party chief and its mayor, bowed deeply at a news conference to apologize.
