Summary

A 33-year-old croupier is accused of overpaying his brother-in-law at the table. The brother-in-law would ask him to break a HK$10,000 chip into smaller denominations at blackjack, and the croupier would hand back six HK$5,000 chips, HK$30,000 for HK$10,000. Between 25 and 29 July 2026 it happened nine times, which the casino first estimated at HK$131,000; police put the total since January at about HK$600,000. Casino staff noticed the exchange and reported it to the Judiciary Police the next morning. Officers waited at the table, and arrested both men when they tried it again at a dice table. Each faces one count of fraud and the case was sent to the Public Prosecutions Office on 31 July.

Analysis: surveillance & operations perspective

ANALYSIS

Editorial commentary by Surveillance Intelligence Asia. Opinion: clearly distinguished from the verified facts above.

Colouring up and colouring down at the table is a cage transaction carried out by the dealer, and it is one of the few moments when value changes hands without a game being played. That is what makes it attractive to a dealer working with a relative or friend: no bet, no result, just a count that is wrong.

The credit here goes to the casino’s own staff, who noticed the exchange, and to the speed of the report: police were waiting at the table the next time it was tried.

Lessons (observation, not prescription)

  • Count chips given and received on camera for every change request, so the count can be checked afterwards.
  • Above a set value, a change request should need a call to the pit, not just the dealer.
  • Review change transactions by dealer, not only by table: a pattern that is invisible across many tables can be obvious for one person.
