A CASUAL worker who has been in and out of jail for the past 10 years was again sent to prison yesterday, this time for six years, for robberies carried out in toilets. In mitigation in the District Court, Lam Wah's counsel, Samuel Chan, said Lam's family was not supportive when he was released from prison in late 1992. Lam was convicted after trial on two counts of robbery and one count of theft, which he denied. He was acquitted on six similar charges, to which he pleaded not guilty, because the charges were based only on his caution statements. Sentencing Lam to six years and one month in prison, Deputy Judge Sujanani told him to use the time to sort out his life. Although only 33 he had been in and out of prisons eight times in the past 10 years, the judge said. Earlier, the court heard that Lam had been convicted 31 times since 1978. The court was told that on August 23 last year, Leung But-chui, 42, had been in a public toilet in Yau Ma Tei when Lam punched him in the face and robbed him of a necklace, a bracelet, a leather bag containing a wallet with $200 cash and bank cards. Prosecutor Joseph To said that at 8.15 pm on September 23, another victim, Chan Sau-ching, was about to leave a public toilet in Yau Ma Tei, when Lam stole his mobile phone, valued at $15,000, as well as $800 cash. Mr Chan's abdomen was struck with a hard object before Lam fled, the court heard.
