A former police inspector yesterday was convicted of stealing HK$140,000 from her friend's bank account after teaching her how to prevent ATM-related crimes. Chloe Chan Kit-ying, 29, was found guilty of seven counts of stealing through ATMs, two counts of attempting to do so and one of stealing a pair of earrings, between May 8 and May 23 last year. Tsuen Wan Magistrate John Glass said friend and prosecution witness Lee Sze-man was 'honest and reliable' and Chan took Ms Lee's PIN to withdraw money from her account. He adjourned the case to September 25 for sentencing. Chan is serving a prison term for another theft conviction. The court heard Ms Lee and Chan had been friends for a couple of months when Chan offered to teach Ms Lee how to protect herself from ATM crimes and asked her to demonstrate how she withdrew money. Ms Lee withdrew cash in Chan's presence and Chan had told her she 'had not done a good job'. On May 9, Ms Lee tried to withdraw money but she was informed she was using the wrong PIN and referred her to the bank. The bank sent her a new number but she never received it. Ms Lee discovered through her online banking service that HK$140,000 had been withdrawn from her bank account via ATMs - HK$20,000 a day on seven consecutive days between May 17 and May 23. On the earring theft conviction, Ms Lee said she had gone with Chan to see a jewellery merchant on May 15. Chan had tried on a HK$2,500 pair of black pearl earrings and praised their beauty. The jeweller found the earrings missing five days later. Ms Lee said she later saw Chan wearing them.
