North China's Inner Mongolia says 27 officials have been penalized over the wrongful conviction and execution of a man 20 years ago.

Feng Zhiming, one of the blacklisted officials responsible for the wrongful conviction of Huugjilt, is suspected of job-related crimes and is subject to further investigation.

Feng is a former deputy chief of the public security bureau in Xincheng District in Inner Mongolia.

The other 26 officials received administrative penalties including admonitions and records of demerit.

The wrongful conviction of Huugjilt is one of the most notorious cases of judicial injustice in China in the recent decades. The teenager was declared guilty of raping and then murdering a woman in a public toilet, and subsequently executed. He was posthumously acquitted of the crimes in December 2014.

The real perpetrator, Zhao Zhihong, was apprehended in 2005. He was given death penalty last year.
