An assistant bank manager who swindled his employer out of almost $3.5 million was jailed for two years and nine months yesterday. Robert Chiu Law-but was driven to crime after incurring huge credit-card debts in a failed attempt to save his marriage, his lawyer Alan So told the District Court. Mr So said Chiu, 39, started making bogus mortgage loan applications, forging the signatures of his Bank of Nova Scotia clients, in 1994. Yesterday, Chiu admitted four charges of procuring an entry in the record of a bank by deception. In sentencing, Judge Richard Hawkes said the offence was well planned.
