Ten mid-ranking officials in Southwest China's Chongqing municipality have been removed from their posts, as authorities continued to investigate an online sex-video scandal that led to the sacking of a district official last year.

The officials included four district- or county-level Party chiefs and the head of a Party discipline inspection committee at the municipality's transportation committee, the municipal government said on its micro blog on Thursday night.

The sacked also include five board directors or executives at five State-owned enterprises, it said.
