BEIJING, Dec. 25 -- The top disciplinary arm of the Communist Party of China (CPC) on Wednesday detailed four corruption cases involving disciplinary officials as part of the anti-graft effort.

The officials received punishments ranging from sentences to sacking after they were found to have been involved in bribery, according to the website of the CPC Central Commission for Discipline Inspection (CCDI).

The case of Wu Hanlin, a former disciplinary official in Meizhou city in south China's Guangdong Province, has been transferred to the court. Wu took bribes of more than 10 million yuan (1.64 million U.S. dollars) during the investigation of many cases in 2012.

Tang Chungang, a former disciplinary official of a Guizhou provincial highway development company, was sentenced to 12 years in May 2013 as Tang was found to have received bribes up to 4.93 million yuan since 2004.

Zhu Mingyi, a former official with the disciplinary agency in northeast China's Heilongjiang Province, was sentenced to ten years in 2009 as Zhu received or defrauded 600,000 yuan in bribery in 2007.

In addition, Jiang Wei, former vice head of the CPC discipline agency in Guoyang County in east China's Anhui Province, was stripped of his membership of the CPC and removed from his post in 2012 after he was found to have taken bribes, according to the commission.

The CCDI asked discipline agencies at all levels to investigate all cases involving disciplinary officials themselves and show zero leniency to such officials.
