A HUSBAND who left his wife partially blinded following an attack in which she was splashed with acid was yesterday jailed for three years. Taxi driver Poon Kin-ying, 48, beat up mother of two Chiang Yuen-fun, 48, at their Chai Wan flat, the High Court heard. During the assault, he repeatedly struck Ms Chiang with a stool leg until she almost passed out. At one stage, he also threatened her with an open bottle of cleaning fluid, which splashed her leg and face. The attack, which left Ms Chiang in hospital for two weeks, came after the couple's 25-year marriage hit the rocks. Poon claimed his wife had been having an affair and said he had hit her in a heated row after she told him to use prostitutes. The couple have since divorced. The attack left Ms Chiang with a broken arm, extensive bruising and conjunctivitis. She had to undergo a skin graft to her ankle and has lost 10 per cent of her vision in one eye. Deputy Judge Burrell told Poon the 'terrifying experience' would remain with his victim for a long time. 'It was undoubtedly a cowardly armed attack on a defenceless woman,' he said. 'Men who resort to serious physical violence because of frustration and anger cannot expect mercy from the courts simply because their frustration and anger arises out of their wife's infidelity.' The attack happened after Ms Chiang, a garment factory worker, returned home shortly before 10 pm on March 10 last year to find her flat in darkness. Poon hit her more than 10 times on the head, body, hands and feet before dragging her into the living room, where he continued the assault. The taxi driver admitted one count of causing grievous bodily harm with intent. But he denied throwing corrosive fluid with intent and the charge was left on file. Defence counsel Andrew Raffell said Poon was remorseful and had insisted on pleading guilty even though his ex-wife had refused to give evidence against him in a trial.
