Another source at the Shanghai Municipal People's Prosecution Service said that Yan is suspected of having taken about 200,000 yuan ($31,850) in bribes, given by suppliers of trading equipment to the exchange, including hardware and software.

Yan, who is still under investigation, was responsible for the exchange's IT system.
