LAKE CITY, Fla. - A Columbia County Fire Department volunteer is accused of making fraudulent charges on a department fuel card.

Over $7,500 worth of illegitmate charges were made on the card. Austin C.Kazmierski was arrested and charged with grand theft. He suspected of using the card to not only fuel his personal vehicle but also letting his friends gas up their cars.

Detectives viewed video surveillance from the stores where the card was used, according to a news release from the Columbia County Sheriff's office.

Police say additional charges are possible since the accounting process isn't complete. Interviews with additional suspects that may have also received fuel are being completed.
