A distressed wife was jailed for eight months yesterday for stealing her husband's credit card to go on a shopping spree in revenge for his extra-marital affairs. The District Court heard that Yu Sau-wai used her husband Cheng Kwok-wai's HSBC Mastercard to make 18 purchases totalling HK$83,627. Judge Pang Chung-ping said that the 18 counts of obtaining property by deception admitted by Yu were not "usual and typical" as her primary motive was revenge. But he said: "Credit card fraud is no doubt a serious crime." The court heard that Cheng had an affair after the pair were married in 2008. In revenge, Yu, 36, took his credit card from a drawer at their Ma On Shan home and forged his signature to buy jewellery, Louis Vuitton handbags, mobile phones and cosmetic products from shops in Ma On Shan, Mong Kok and Tsim Sha Tsui. The purchases were made between June and July 2011. Yu initially denied responsibility when Cheng questioned her about the card use after he received a monthly statement showing credit card transactions of about HK$75,000, the court heard. But Yu later paid him HK$6,000 in compensation. In mitigation submissions, lawyer James Li asked the court to take a "global view" of the charges. He said Yu was "not in a position to pay compensation". The court heard that Yu had an abortion in 2005 because her unborn baby was found to have genetic defects. In 2007, she was given a community service order for theft.
