Wei Pengyuan was found to have bought several flats and used one of them to store a huge pile of cash, according to media reports
Investigators found more than 200 million yuan (HK$252 million) in local and foreign currency at the home of a mainland energy official - the biggest haul of corrupt cash since the establishment of the People's Republic.
It confirms media reports from earlier this year that Wei Pengyuan, deputy director of the National Development and Reform Commission's (NDRC) coal department, was under investigation as part of the sweeping crackdown on corruption in the energy sector.
