Residents of a luxury home in Hong Kong have lost jewellery worth HK$751,000 after a break-in while they were dining downstairs.

Police received a report of the break-in at 9.50pm on Saturday from a 69-year-old man, the owner of the two-storey house at Greenwood Terrace on Sui Wo Road in Fo Tan.

He said his master bedroom had been broken into and a jewellery box pried open, with 10 necklaces, 15 rings and six brooches missing.

The loss was estimated at about HK$751,000 (US$95,838).

The man said he had checked the bedroom around 6pm before joining his family for dinner in the ground-floor living room.

When he later returned, he found the bedroom door locked from inside. After unlocking it, he discovered the room had been ransacked and the jewellery stolen.
