'Laser scam' gamblers to keep ?1m
The trio - a Hungarian woman and two Serbian men - were arrested in March but police have apparently decided that they did not break the law.
A laser scanner linked to a computer was allegedly used to gauge numbers likely to come up on the roulette wheel.
But police said the case had now been closed, with no charges brought.
Simson Garfinkel's Database Nation describes a similar incident when a gambler observed slot machines to predict the randomness generated by machines and then played and won a sizeable sum but he was not allowed to keep the money.
