On Friday, Gainesville police arrested 20 year old Ushie Rashard Alungbe trying to use two counterfeit twenty dollar bills at a high school football game.

They say he admits to making between $4000 and $5000 worth of fake twenties. Fake money that could now be floating around town.

"He spoke with law enforcement, he told us he worked downtown and that he had been passing twenty dollar bills downtown," said Gainesville Police Sergeant Keith Kameg.

So how can you tell if the money in your wallet your is fake?

Real twenties have a "security thread". That's the vertical line you see when you hold the twenty up to light.

Police say the fake twenties were also cut poorly and some of the ink smeared when they got wet.

The secret service is investigating the charges.
