A debt-ridden man who robbed a convenience store with a water-filled beer bottle he claimed was a petrol bomb was yesterday jailed for five years and four months. Deputy Judge Derek Pang Wai-cheong of the Court of First Instance told Kwok Cheuk-man it was a planned robbery and called for a deterrent sentence. Kwok, 38, pleaded guilty to one charge of robbery and one of resisting arrest. At about 3pm on July 22, the defendant, wearing a baseball hat and a surgical mask, entered a convenience store in Wing Lok Street, Central. The court heard he was holding a bottle, which he said was a petrol bomb, in one hand, and a lighter in the other. Kwok ordered a store employee to take the cash from the register and put it into his rucksack. He fled with $182 and jumped into a taxi. Shortly afterwards, Kwok's taxi was stopped at a police roadblock. Officers had to subdue him. Kwok said he committed the robbery to pay off large debts.
