BEIJING - Chinese prosecutors have launched separate investigations into four former law enforcers suspected of corruption, the country's Supreme People's Procuratorate (SPP) announced on Tuesday.

The four suspects are Sun Hai, former deputy chief of the provincial prison administration in Hebei; Liu Xianming, formerly chief of police in Ceheng County of Guizhou; Wu Jianming, a former judge in Nancheng County of Jiangxi; and Lin An, a former prosecutor stationed at a local prison in Inner Mongolia.

Sun, Wu and Lin are suspected of taking bribes, and Liu of releasing people from detention without authorization.

Also on Tuesday, the SPP said another judiciary worker, Yang Moulin, formerly president of an intermediate court in the city of Xuancheng of Anhui, has been prosecuted.

Local prosecutors accused Yang of taking advantage of his position and embezzling public funds.

Yang is also charged with requesting and accepting money and gifts from people in exchange for seeking benefits for them, according to the SPP.
