Chinese prosecutors investigated nearly 2,800 judiciary workers suspected of corruption among other work-related crimes in 2009, a report released Monday said.

The annual report on China's legal system construction in 2009 published by the China Law Society said prosecutors at all levels disallowed the arrest of more than 123,200 criminal suspects last year.

Moreover, prosecutors decided not to prosecute 33,000 criminal suspects, as they strove to protect citizens' legitimate rights, the report said, adding that they also corrected more than 25,600 cases of wrongdoing.

The China Law Society is an academic organization of legal experts and practitioners. Headquartered in Beijing, it has over 410 local branches across China.
