The day after his 2005 sex attack acquittal "The Sun" alleged that Hann had agreed to lose his opening match against the 1997 world champion Ken Doherty at the China Open to one of its undercover reporters in return for £50,000. The story had been held back so it would not prejudice the outcome of Hann's trial. A hearing at the World Professional Billiards and Snooker Association (WPBSA) was convened after its panel was shown transcripts of video and audio footage of the meetings which took place between Hann and the undercover "Sun" journalists in March and April 2005. In September, he entered the Grand Prix tournament, before he withdrew one month later on medical grounds. Hann submitted a medical certificate and received a £3,000 prize fund from the WPBSA. Hann later failed to attend the first round of the UK Championship for undisclosed reasons.
