A chief inspector was allegedly caught red-handed operating illegal bookmaking activities from his Tin Shui Wai home and found to have unexplained income amounting to $10 million, the District Court heard yesterday. Raymond Tsang Chung-chim, 41, has pleaded not guilty to dealing with property known or reasonably believed to be the proceeds of an indictable offence, or money laundering. He was the Kwai Tsing district operation officer and handled crackdowns on vice-related activities, illegal gambling and drug trafficking in the Kwai Chung and Tsing Yi districts. He remains a serving police chief inspector. Prosecutor John Marray told Judge Alan Wright that in September 2003, officers from the Organised Crime and Triad Bureau searched Tsang's home. They found him seated at a computer table with two monitors logged on to Easybets and Macauslot, both internet gambling sites. The television was broadcasting the day's horse racing live. Suspected betting records were found along with other illegal bookmaking items. Tsang was arrested. Mr Marray said a police gambling expert believed the betting records involved soccer gambling, off-course horse racing and Mark Six. Information was also downloaded from the defendant's two computers. Betting records for the race of September 17, 2003, involved stakes worth $49,700. The financial investigations division under the Narcotics Bureau investigated Tsang's seven bank accounts and found unexplained deposits amounting to more than $10.95 million and unexplained withdrawals amounting to $10.39 million between January 1999 and September 2003. Tsang's monthly taxable income on his salary tax returns averaged $88,467 per month between 1988 and last year, the court heard. Mr Marray told the court that the volume of unexplained deposits and withdrawals in Tsang's seven bank accounts and the way the money was deposited and withdrawn 'bear the hallmarks of money laundering'. He had accounts in HSBC, Hang Seng Bank and Wing Hang Bank and a large number of parties named as either depositors or beneficiaries, Mr Marray said. The trial continues today.
