Two deputy directors of the public security bureau in southwest China's Chongqing Municipality will be prosecuted next month, said Chongqing's Procurator Yu Min Thursday.

Wen Qiang, formerly the No. 2 figure in Chongqing police and director of the justice bureau before he was arrested, and Peng Changjian are among the 52 public servants who are being investigated for shielding gangs, said Yu.

Among the 52, 49 people would face charges of embezzling public funds and taking bribes while the other three would face charges of misconduct in office.

Among them, 29 were police officers and 30 were officials at the county and provincial department levels.

Wen has allegedly provided a "protective umbrella" for local gangs, and was also suspected to be involved in rape, money laundering, disguising or concealing the proceeds of crime, illegally holding firearms, offering loans in high interests, forging official and enterprise seals, introducing women to prostitution and taking huge bribes.

Peng allegedly took 820,000 yuan (120,000 U.S. dollars) and 100,000 HK dollars (12,900 U.S. dollars) in bribes and offered assistance to illegal business operations.

Yu Min also said the procuratorate has issued arrest warrants for 814 suspects in the municipality's crackdown on gang-related crimes.
