Robbers posing as an expectant father and a patient ransacked clinics and tied up nurses, a court heard yesterday. Chan Hing-lun, 22, and Choi Yuk-kwan, 25, were jailed for six years after pleading guilty to robbery. At night on November 3 last year, nurse Kwok Yun-ying was working in the reception area of the San Po Kong clinic when Choi walked in. When she asked him what he wanted, he said he was waiting for 'the baby'. Chan entered the clinic a couple of minutes later and the men disappeared into the building together. Lo Miu-yin, who operates the clinic, was alone in her office when the pair burst in. One was wielding a knife, the Court of First Instance heard. Choi took Ms Lo's wallet while Chan returned to the nurses' station, where he tied up and gagged Ms Kwok. The pair ransacked the office and made off with $2,500 of the clinic's takings. Ten days later, they raided a clinic in Boundary Street, Kowloon. Chan posed as a patient in need of treatment. Choi arrived afterwards, pretending to be the husband of a patient. Chan, emerging from the examination room, then faked a fainting spell in the reception area. When a doctor rushed to help him, the two men whipped out knives. Again, staff were bound while the clinic's office was ransacked. The pair escaped with $8,000. In mitigation, the pair said that unemployment had driven them to crime. However, Deputy Judge Gareth Lugar-Mawson rejected the excuse.
