Wife and daughter held after man escapes through window Police arrested a Mong Kok woman and her daughter yesterday after they allegedly assaulted then tied up the woman's 62-year-old husband in an apparent attempt to stop him travelling to the mainland to visit his mistress. Police made the arrests at about 8.20am after the man managed to free himself and escape from a third-floor unit on Lai Chi Kok Road, Mong Kok, where he had been held for more than nine hours. 'The victim managed to untie himself, climb out of the kitchen window of the unit and climb down the drainpipes before making a report to police,' a police spokeswoman said. The man was taken to Kwong Wah Hospital for treatment for bruises to his face and legs, and was later discharged. Police said the woman, 47, and her daughter, 23, were arrested for assault and unlawful detention over the incident, which occurred at about 11pm on Monday night when the man returned to the flat. According to police investigations, the couple lived separately, although it was not known whether they were divorced. A police source said the man returned to the unit to pick up his home return card because he wanted to go to the mainland to meet his mistress. Police said the man then had a dispute with his wife and daughter. 'In the heated argument that followed, the victim was punched and then tied up. He was not allowed to leave the unit,' the spokeswoman said. The woman and her daughter only realised he had escaped when officers arrived at the unit. Last night, the pair was being detained at Mong Kok police station for questioning and no charges had been laid. The woman lives with her eight children in the flat and the family lives on welfare, according to a government source. A spokeswoman for the Social Welfare Department said social workers were now following up the case. The incident is the latest in a string of domestic violence cases in Hong Kong this year. Police figures show the number of domestic violence cases rose by 31 per cent to 719 in the first six months of this year, compared with the same period last year. There were 1,274 domestic violence cases for the whole of last year.
