A TEENAGE sales assistant who left a safe unlocked so her boyfriend could burgle the watch shop where she worked was yesterday sent to a training centre. Delivering the sentence, Judge Gould said Lam Wing-yi's remorse came too late. Lam, 18, covered her face with her hands and cried. Her mother, sitting anxiously in the District Court's public gallery, raised her hand and requested a few words with the judge. But Judge Gould replied that the defence counsel, Roderick Woo, should have told him everything the mother wanted to say. 'I have considered the suggestion of a probation order. But, when I look back to the first day of the trial, you showed no remorse then,' the judge told the teenager. 'It strikes me that you feel remorseful only when facing the punishment.' Lam, her boyfriend Yip Chi-wai, 20, and Wong Man-sing, 29, were charged with burglary. The men had admitted stealing $6,950 and 322 watches worth $630,000 from the City Chain store in Wan Chai on November 10 last year. Wong was sentenced to 27 months in jail and Yip was sent to a training centre. Lam had denied the charge. The court heard that Lam had agreed to join the racket after considering the matter for a month. Yip then stole the shop's key when he visited his girlfriend on November 8. The next day, Lam left the shop's safe unlocked before going to Macau with her colleagues. She also turned off the security alarm. Yip paged Lam to make sure no staff were left behind, then he and Wong burgled the shop in the early hours of November 10. Judge Gould said Lam had helped the burglars gain access to the shop and had obviously acted in breach of trust. Mr Woo told the court Lam's mother had quit her part-time job so she could spend more time with her daughter. The mother had opposed the relationship between Lam and Yip, who met in 1991. 'But you took no notice of your mother's advice in 1991; I cannot see that you will take notice in future,' the judge told Lam.
