A mid-level local official in north China has been accused of accepting bribes worth over 100 million yuan ($14.47 million), and illegally owning four guns — unusually serious charges for someone of his rank.

Ma Chaoqun, a former deputy party secretary at a state-owned water company in the resort city of Qinhuangdao, allegedly accepted the bribes from 1998 to 2014, according to charges announced at a three-day trial that ended Wednesday.

Interestingly, according to court transcripts, Ma could not explain the origin of nearly 72 million yuan worth of alleged bribes. While the reason for that is unclear, officials involved in past corruption cases have sometimes withheld explanation in order to avoid implicating others.

The court said it would announce its ruling soon.
