Ao allegedly set up shell companies a network of secret bank accounts in Hong Kong and the British Virgin Islands with the help of friends and family members to launder bribe money. Ao's father Ao Veng-Kong, brother Ao Man-Fu, and sister-in-law Ao Chan Va-Choi were charged with setting up overseas bank accounts and shell companies for Ao Man-long to handle kickbacks. The total deposits in more than a dozen Hong Kong bank accounts under his father's name exceeded HK$157 million as of December 2006. The three family members pleaded not guilty, claiming Ao Man-long opened the bank accounts for them. All family members were sentenced to prison terms by a decision of the Macau Court of Second Instance on 30 October 2008.
