Macau casino junket figure Cheung Chi-tai appeared in a Hong Kong court this week to face three charges of money laundering.

Last December, Hong Kong authorities froze assets belonging to Cheung, who is reputed to be one of the main investors in the Neptune Group junket operation, although Neptune has claimed Cheung no longer has any stake in the company. Cheung’s wife was similarly detained in April 2014 and had her assets frozen over suspected money laundering activity.

The South China Morning Post reported that the 54-year-old Cheung turned himself in to police on Monday and appeared in Eastern Court on Wednesday. Cheung was arrested and released on HKD 200k (US $25,800) bail pending his next court appearance on Sept. 24.

Cheung’s charges, filed under the Organized and Serious Crimes Ordinance, relate to deposits made to his Hong Kong bank accounts that police allege Cheung knew were “in whole or in part, directly or indirectly” the proceeds of an indictable offence. The total sum made via these deposits between 2004 and 2010 comes to HKD 1.79b ($231m).
