RIVERSIDE, Mo. -- The Argosy Casino in Kansas City reports a $100,000 loss following a counterfeit chip scam.

The Missouri Highway Patrol confirmed that a man scammed the Argosy Casino off Interstate 635 in Riverside using counterfeit $100 chips.

A 36-year-old suspect was arrested by state gaming agents last week, but he has not been charged. The man is under investigation, accused of making hundreds of fake $100 chips, then cashing them in for more than $100,000.

"I'm surprised they were able to do it and get away with it. That's a large sum of money," said Brenda Terrill, a Raytown resident who was gambling at the Argosy Casino on Monday.

During their monthly inventory, casino officials realized they had extra chips and discovered the fakes, which were slightly thicker than the casino's chips, officials said.

Argosy Casino Hotel and Spa general manager Ameet Patel said they studied surveillance video and identified a suspect. When that suspect showed up last week, investigators arrested him.

"I guess with the state of the economy, people are trying new ways to provide for themselves," said Lawrence resident and casino patron John Griffin.

Highway Patrol has not yet released the suspect's name but said the investigation is ongoing.

Patel said about 1,100 phony chips had been discovered so far.
