Hong Kong police still hunting diamond heist teen

Hong Kong - Hong Kong police are on the hunt for a teenage girl on Monday who is said to have made off with a multimillion-dollar diamond necklace over the weekend.

No arrests have been made so far, police confirmed, after the robbery on Saturday at a jewellery shop reported to be in southern Kowloon.

Around 15:00, three well-dressed adults distracted staff while a girl estimated at between 12 and 14-years-old stole a key, opened a locked cabinet and slipped the necklace worth $4.6m into her pocket, the South China Morning Post reported.

The trio, two women and one man aged between 30 and 40, stayed on in the store while CCTV footage showed the girl calmly leaving the mall compound.

"The necklace was embedded with more than 30 diamonds totalling about 100 carats," a police source told the newspaper.

After spending more than 30 minutes in the shop - reported to be the Emperor Jewellery shop in southern Kowloon - the four left without buying anything, the South China Morning Post reported.

Detectives described the heist as "very well planned”.
