State officials were responsible for more than 4,000 cases of abuse including torturing of suspects from 2001 to last year, national prosecutors said yesterday. The deputy procurator-general of the Supreme People's Procuratorate, Wang Zhenchuan , said prosecutors had uncovered 4,029 cases of rights violations by officials during that period, and 16 per cent were considered serious. Mr Wang said the cases ranged from torture of suspects, extracting confessions by force, illegal detention and searches, and tampering with elections. Mr Wang noted the Supreme People's Procuratorate had launched a year-long campaign this month to investigate abuses committed by government officials, and had set up a public hotline to encourage complaints from victims. He also said at least three officials would soon face trial for a lantern festival stampede in Beijing in February which killed 37 revellers. Chen Lianfu , a deputy director of the Anti-Malfeasance Office of the Procuratorate, said Sun Yong , head of a police station in Miyun county, Beijing, and Chen Bainian , political commissar of the station, were both arrested in February. Wang Haiyan , head of the Miyun county Cultural Bureau, was also held but has been granted bail.
