Volusia County Sheriff's deputies said the managers of a Winn-Dixie store in DeLand became suspicious when they noticed store profits took a dive.
"They had taken a look at their financial reports and discovered there's an unusually large number of coupon transactions that really affected their bottom line," said Volusia County Sheriff's spokesman Brandon Haught.
Store managers estimated there was a $23,000 discrepancy. They started investigating on their own and authorities said it led them to a store clerk.
"One of their employees had been cashing fraudulent refunds based on coupon codes and had been doing it for many months," said Haught.
The Sheriff's Office was advised of the internal investigation and deputies confronted Ibilola Badmus. Badmus admitted to stealing the money, according to investigators, saying she needed cash to pay for a sick child's medical bills. Investigators said Badmus told them she still had $3,000 of the stolen money left in her bank account, which she returned.
Deputies said Badmus is a citizen of the United Kingdom, where authorities have been notified of her arrest. Badmus, 30, of Sanford, was arrested and charged grand theft over $20,000. She has since bonded out of the Volusia County Jail.
