MIAMI GARDENS, Fla. – A beer vendor was arrested Sunday at Hard Rock Stadium after using a Square reader to charge more than $700 to a fan's credit card during a Miami Dolphins game, police said.

Nathaniel Collier, 33, faces charges of third-degree grand theft and possession of a skimming device.

According to an arrest affidavit, the victim ordered two beers from Collier during Miami's 30-10 loss to the Los Angeles Chargers and gave him his credit card to pay for them. But police said Collier used his personal card reader to charge the victim $724.

The victim was notified of the charge by his bank a short time later.

Collier was taken into custody without incident. Police said he had a Square credit card reader in his possession.

The subcontractor that employed Collier, Rocket Man, provided Local 10 News with a statement regarding his arrest.

"As the chosen provider of walking vendors across dozens of stadiums, we take the matter of security extremely seriously, and train and monitor our vendors to safeguard our customers. Our onsite supervisor contacted the authorities immediately upon learning of the overcharge on what was Mr. Collier's unauthorized personal device. The credit card company issued a full refund and the guest incurred no loss. The suspect's employment has been terminated. As this is an open legal action, we cannot offer further comment."
