An official in Southwest China's Yunnan province has been dismissed from his post after images showing him taking part in group sex were posted online, local disciplinary authorities confirmed on Thursday.

The Kunming disciplinary inspection committee released a statement saying that the official, identified only by his surname Cheng, has "severely damaged social morality" through his behavior.

Cheng, an official with the Kunming commission of development and reform, was also expelled from the Communist Party of China.

Photos showing Cheng taking part in group sex were posted online on the morning of July 31. Cheng went to local police later that day, claiming that he had been blackmailed for 63,000 yuan ($10,000).

After an investigation, the Kunming Public Security Bureau said in a statement on Tuesday that a group of four people lured Cheng into participating in the act and recorded him using a hidden camera.

The four people have since been arrested, according to the statement.

Cheng's case was revealed shortly after another official in Central China's Henan province was suspended for similar reasons.

Tian Hanwen, a lawmaker in Ruyang county, became notorious overnight after photos of him having sex were posted online by an anonymous woman, who accused Tian of "taking advantage" of her.

The woman said in her post that Tian made several unwanted sexual advances toward her after meeting her in 2006, promising to help her find a job.

Tian never fulfilled his promise, the woman said, adding that she has not been his only victim.
