A couple, charged earlier this month with abetment of cheating a man of $38,800, were accused yesterday of 28 more cheating offences.
Ong Choon Lin, a 66-year-old Singaporean, and his Malaysian wife, Ng Kim Yew, 60, are now said to have duped six victims into giving them $657,068.
The retirees allegedly conspired with each other to deceive the victims into believing that a spiritual master from Thailand or Tibet would personally write a talisman dedicated to the victim.
They allegedly thus induced the victims dishonestly to hand over various sums of money, ranging from $688 to $38,800 each time.
The victim who gave the most - $308,688 - was allegedly cheated from 2004 to March last year.
Two others were allegedly cheated of $100,580 and $137,800 while the smallest sum was $11,000.
Deputy Public Prosecutor Tay Jingxi suggested bail of $500,000 but the couple's lawyer Anil Balchandani said the amount was excessive and proposed $25,000 instead.
He added that Ng was unwell and had been hospitalised twice.
District Judge Eddy Tham fixed bail at $300,000 each. The couple's passports have been impounded.
A pre-trial conference is scheduled for April 28.
The maximum penalty is 10 years in jail and a fine for each charge.
