AN unemployed man who held up nine boutiques was yesterday sentenced to 13 years' jail by the High Court. Mr Justice Bewley accepted there was no violence, and a relatively small amount of money was involved but said there were no mitigating factors. Wong Ka-wai, 22, had denied nine counts of robbery and one of carrying a firearm with intent to commit an offence but was found guilty on all charges. The robberies occurred between March 1 and June 11 last year at boutiques in Tsim Sha Tsui and Mongkok. On each occasion, Wong either pointed what appeared to be a pistol at the sales assistant or showed her its butt. He escaped with more than $30,000 incash and other valuables. Wong, represented by Rupert Spicer, said he had been framed by police. In mitigation, Mr Spicer said none of the victims had been physically harmed.
