Hong Kong authorities will review how the assets of prospective buyers of subsidised flats are assessed, after it emerged the former father-in-law of slain model Abby Choi Tin-fung owned one such home at the same time a HK$73 million (US$9.2 million) property was bought under his name.

Permanent Secretary for Housing Agnes Wong Tin-yu revealed the move on Monday when lawmakers questioned her about loopholes in the eligibility vetting system for subsidised flats after details of the property holdings of the Kwong family came to light.

While Wong refused to comment on individual cases, she added that “after such an extreme example”, the government would review its policy.
