Staff at the old people's home where an 80-year-old woman had to be tied up to protect her from sexual assault were interviewed by social welfare officials yesterday. The South China Morning Post learned yesterday that the woman, whom staff said had a habit of taking off her clothes, had been sexually assaulted by at least three male residents. Social Welfare Department officials told the subsidised home in Tuen Mun to pay more attention to the woman and to restrain her from wandering only at meal times, when staff were stretched. The case has not been reported to police because management did not know if the woman's removal of her clothes had invited the assaults. Due to a shortage of manpower, the staff tie the woman to a chair to prevent her from wandering, instead of giving her proper care. A social welfare spokesman said it was agreed that more carers should be allocated to the women. 'We were told that counselling had been given in the home about respecting fellow residents,' the spokesman said. 'The most important point is that the family of the woman have been told of what happened and had no complaints about how the incident had been handled.' The spokesman said that subsidised homes were free to run their operations and they would not be required to report problems which they believed they had under control.
