Chinese procuratorates at various levels approved the arrest of 811,102 criminal suspects of various kinds in 2004 and prosecuted 867,186, up 8.3 percent and 9.3 percent respectively year-on-year, said a top procuratorate official Wednesday.

Jia Chunwang, procurator-general of China's Supreme People's Procuratorate, disclosed the figures while delivering a report to the annual session of the National People's Congress.

He described last year's security situation as being still "grave" in his report and said continuous efforts have been made to crack down crimes such as those involving serious violence and endangering national security.
