BEIJING - Chinese prosecutors will intensify supervision of police criminal investigations, according to a report Saturday.

"A system which allows prosecutors to work or set up an office in police stations in main urban areas, rural-urban fringe areas and areas with a high incidence of criminal cases will be piloted," China's Procurator-General Cao Jianming said.

Cao made the remarks when delivering a report on strengthening supervision on investigation and safeguarding judicial fairness at the bimonthly session of the National People's Congress Standing Committee, which will conclude on Monday.

Meanwhile, the procuratorial agencies will establish rules to supervise judicial measures and investigations that "restrict personal freedom."

The prosecutors will be strict with evidence, demanding flawed evidence be redressed and illegal evidence eliminated, Cao said.

Procuratorial agencies will also push forward a reform that will strengthen prosecutors' supervisory role in the investigations of major and difficult cases.

According to the report, procuratorial agencies wrote statements for correction to about 175,000 investigative activities suspected of breaking the law since 2013. More than 91 percent of the recommendations were adopted by investigators, it added.
