NEW YORK (AFP) - Jewellery worth US$750,000 (S$1.05 million) was stolen from New York Knicks star Derrick Williams after a night of partying at the player's luxury apartment, US media reports said on Sunday, citing law enforcement sources.

The New York Post reported that the theft occurred after he invited a group of revellers - including two women he had just met - back to his Manhattan apartment on Friday after an evening at a local nightclub.

According to law enforcement sources, the two women plundered jewellery worth US$750,000 from a suitcase in a closet before leaving the apartment.

Williams discovered the theft on Saturday and alerted police. The Post report said police are studying the incident to see if it is linked to a series of similar cases in New York involving women preying on wealthy men with a taste for expensive jewellery.

The report said earlier this month, a watch dealer had a US$590,000 timepiece swiped from him by two women he met at a New York strip club.

Williams, 24, declined to comment on the theft after Saturday's defeat of the Chicago Bulls at Madison Square Garden.

"I don't want to talk about it," he was quoted as saying. "It's still up in the air."

He often posts pictures of expensive watches he has acquired on his social media accounts. "I love watches man," he wrote in one post. "Invest and watch it multiply."
