A former top prosecutor in Linxiang, Hunan province, has been expelled from the Communist Party of China for taking illegal drugs and other violations of Party rules, the city's anti-graft body said on Tuesday.

Liu Qunlin, former secretary of the committee for disciplinary inspection and the procurator-general in Linxiang, was placed under investigation in August. He was removed from his post on Aug 11.

Zhang Mingzhi, an official with the city’s publicity department, said Liu was dismissed for aiding and abetting the drug use of another city official, according to The Paper, which reports on anti-corruption news.

Gong Weiguo, 43, the former mayor of Linxiang city, was removed from his post in April. The local government told Xinhua then that Guo was being investigated over suspected drug use. Gong was appointed as deputy Party chief and mayor of the county-level city in December 2011.

The anti-corruption watchdog in Hunan also announced on Tuesday that Cao Qingsong, former city police chief, was expelled from the Party and removed from his posts for breaching austerity rules and committing adultery.
