A man described by a judge as a drug addict was jailed for 71/2 years yesterday for robbing 16 women aged 42 to 84 to feed his heroin habit. Sentencing Ray Lee Wai-yip, 37, in the Court of First Instance yesterday, Deputy Judge Peter Longley said five of the victims were over 70 and two were over 80. The court heard that Lee, who pleaded guilty on Thursday to 16 charges of robbery, had grabbed his victims from behind while they were in, entering or leaving lifts or in building corridors. He took property valued at HK$87,000. Noting that Lee had been jailed twice in the past 10 years for robbery, Judge Longley said: 'The experience of prison did not make you better yourself.' Lee claimed in a letter to the court that he was remorseful and would be good in future, which the judge described as 'worthless'. The offences were committed between March 17 and May 7 this year in various districts. Each victim was alone apart from one, whose 84-year-old husband was with her in a lift. Ten of the victims sustained minor injuries. Lee was first jailed in 1998 for eight years for robbery. He committed more robberies in 2005 for which he was jailed for six years. He was released in February for good behaviour under the supervision of two correctional services officers and a social welfare officer. After committing the latest offences, he was ordered to serve another year of that sentence, which he is currently completing.
