A 44-year-old croupier and three others were charged in court on Wednesday with cheating at play in Marina Bay Sands (MBS) casino.

Yeo Eng Seng, who works as a dealer, allegedly colluded with Ho Keng Guan, 43, and Lim Boon Kwang, 42, to cheat the casino while playing Baccarat on Monday.

He is said to have provided the sequence of cards in advance to the two men to deceive the MBS casino into believing that their respective wager of $3,900 and $1,900 cash chips on "banker bet'' was honourable, and induced the casino into paying them chips totalling $5,800.

A third patron, Lee Mee Leng, a 40-year-old Malaysian woman, is alleged to have colluded with Yeo and Ho to get cash chips of $4,500 as winnings for herself earlier on April 6. She is said to have known the sequence of cards in advance through Yeo's position as a dealer and duped the MBS into believing that her wager on "player bet'' was honourable.

All except for Yeo are represented by Mr Eric Tin. All four were remanded at Central Police Division for further investigation.

Police seized cash of $10,000, casino chips worth $14,675 and seven mobile phones as case exhibits in the course of investigation. The four will appear in court again on May 15.

If found guilty, each could be fined up to $150,000 or jailed for up to seven years or fined and jailed.
