The old invisible ink cheat.

According to reporting from The Day, a New Jersey gambler was busted early Sunday for allegedly cheating at the Mohegan Sun. His method according to the police: marking the cards with a ink-like substance that could only be seen with special contact lenses.

Fifty-nine-year-old Bruce Koloshi, who hails from Summit, New Jersey, also allegedly used the tactic in a game of stud at a casino in Louisiana in August. Koloshi has been caught cheating before in Las Vegas, Reno and in the state of Iowa.

The Day reported that after his most recent arrest in Connecticut he gave authorities a fake name, though his fingerprints eventually revealed to the cops his real name.

He reportedly has been charged with a slew of crimes, including cheating, conspiracy, criminal impersonation and “being a fugitive from justice when the computer check revealed that Louisiana state police had issued a felony arrest warrant for him.”

For the alledged crimes, he is being held on $510,000 bond.

His arraignment is scheduled for Monday in Connecticut’s Norwich Superior Court.

It’s unclear how much he was able to win using the invisible ink.

As reported by The Advocate, Louisiana police described the ink in Koloshi’s warrant. “The markings were small finger pad markings made from invisible luminous ink. The markings were invisible to the naked eye and could only be seen when viewed with the infrared filter.”
