The former deputy head of the provincial environmental watchdog in Hebei has been charged with taking bribes along with another 10 officials, amid a tide of senior officials in environment authorities being accused of corruption since 2014.

Li Bao had taken advantage of his leading position since 2009 to get benefits from illegal trades such as helping an environmental technology company in bids for building 196 air quality monitoring stations, Procuratorial Daily reported on Tuesday.

He received property worth around 14 million yuan ($2.3 million) and $60,000 in cash, it said, adding that another 10 officials have been charged in the group corruption cases, and six of them worked in leading positions in provincial environmental protection department and its branches.
