Three primary school girls aged from 10 to 12 have been arrested by police in relation to an alleged theft of HK$5 million worth (US$636,975) of jewelry.

The case came to light when a 39-year-old local woman called police on Monday night to say two diamond necklaces and a diamond bracelet worth HK$5 million had disappeared from her handbag in a flat in a public housing estate in Kowloon’s Wong Tai Sin, Apple Daily reported.

The victim was a married woman surnamed Lee who works for an investment bank. She recently moved in to the public housing flat in Lower Wong Tai Sin Estate, where a 10-year-old girl and her divorced father live.

It was understood that the victim and the father are friends, but the girl disliked the woman, who moved into the flat in early January. They often had quarrels.

After an investigation, police believed that the girl stole the woman’s missing jewelry.

The girl told officers that she had dumped the jewelry out of a window but later claimed that she gave the necklaces and bracelet to a 12-year-old classmate to look after.

However, no jewelry was found at the classmate’s home.

A third girl aged 12 was also arrested but later released on bail, while the initial pair were still being held for questioning, Sing Tao Daily reported.

Officers had yet to find the missing jewelry.
