A BIG-HEARTED robber gave his victim a $20 taxi fare so he would not be left stranded, a court heard. Ng San-ming, 23, pleaded guilty to robbery and staying in Hong Kong illegally and was sentenced to four years and eight months in prison. He was part of a four-man gang who swooped on a design student and stripped him of his cash and jewellery. On August 23, Wong Sai-ho, 20, was walking past a footbridge in Lai Chi Kok Park when he found himself surrounded by robbers, the District Court heard. One was brandishing a metal pipe, another held a knife. They demanded he turn over his money, and he pulled $140 from his pockets. Ng snatched the cash. But, when the student informed him that the robbery would leave him with no way to get home, Ng returned $20. The robbers then turned and fled, warning their victim not to follow. But the brave student gave chase, shouting for help. The man with the knife spun around and told Mr Wong that he would be killed unless he stopped. Ng was caught after a passer-by saw the commotion and tackled the robber. Thomas Evans, for Ng, said in mitigation that Ng's father was suffering from a lung disease that left him unable to work. But Judge Sweeney was unmoved. 'He did not come here to seek work like so many illegal immigrants,' he said. 'Ng committed robbery as soon as he arrived.'
