The son of a former Hong Kong policewoman killed after robbers barged into her UK home has called on the public to help catch his mother’s killers. A gang of six masked men broke into the Milton Keynes house in January, knocking 64-year-old Leung Hang-yin over before stealing an £8,000 (HK$76,000) Rolex watch and her police long-service medal. They also robbed Hong Kong ID cards and cash, Thames Valley Police said. Leung died 12 days later in Milton Keynes Hospital, Buckinghamshire. Police are treating her death as murder. Mother arrested after neighbour hears children’s cries from locked flat On Thursday Leung’s son Keith appealed to the public to come forward with information that could help catch his “bubbly” mother’s killers. “I would ask them to look into themselves how they would feel if they lost a mother or a sister or indeed someone who is very special to them,” Leung said at local police headquarters. “This is exactly what has taken place in my family and to the wider community.” Mrs Leung responded to a knock at the door at about 6pm on January 31, and found a man outside, police said. Six men rushed past her, knocking her to the floor. One of the men held her down, with his hand over her mouth. While talking to detectives the next day, Leung collapsed and was rushed to hospital. “This is a despicable crime that has targeted a frail woman at home alone,” Detective Superintendent Simon Steel said. Boy, 16, arrested over string of indecent assaults “The burglars had a choice that evening, and they chose to target this house of an elderly female, frail and on her own,” he said. “They made a choice to use violence against Hang, who was a businesswoman, a wife, and a mother; stealing her possessions and her life.” Police urged anyone who saw a car being driven “dangerously or erratically” on the night of the attack to come forward.
