The Supreme People's Procuratorate has made public 12 corruption cases involving prosecutors, vowing to instill discipline with a strong hand.

Wang Yongqiang, a former prosecutor at the procuratorate in Qingdao, Shandong province, was alleged to have trafficked drugs, while Zhou Yong, former head of the office overseeing dereliction of duty at a procuratorate in Wolong district in Nanyang, Henan province, is alleged to have operated a casino.

The top prosecuting department did not provide detailed information about the cases.

It said that a handful of prosecutors have chosen to ignore the Communist Party of China's code of conduct, despite the central authority taking a strict stance on Party governance.

"Some officials in leading positions have deviated from the right path and failed to behave in accordance with the law or the Party's code of conduct," it said.

The top procuratorate urged prosecuting departments across the country to learn a lesson from the cases and reminded them that there will be no letup in improving the governance of the Party and the management of procuratorates.

Cases related to drugs attracted wide public attention last year, with people from a variety of sectors being caught.

Some 39 functionaries have been caught using drugs since a local regulation on drug use among Party members and public servants was rolled out in Hengyang county, Hunan province, in January last year.
