A convenience store owner in Daytona Beach, Fla.was arrested Monday for running a food stamp scam, using tax dollars to stock his shelves.

Bassam Abu Diab and his son Matthew were buying food stamp cards for 20 to 40 cents on the dollar and using them to shop at Walmart and Save-A-Lot stores for items they sold in their convenience store, police said, according the Daytona Beach News-Journal.

An undercover agent sold EBT cards to Abu Diab, which he used to purchase items at other stores and then paid the agent less than half the value of the cards. Federal, state and local officers raided the Abu Diabs’ 4M Food Mart after a 3-month investigation.

“This guy is running a business on the taxpayers back,” said Daytona Beach Police Chief Michael Chitwood, according to local tv station WFTV Channel 9. “It’s a fraud. He’s unscrupulous and clearly he didn’t learn from the last time we hit the store.”

Detectives said Abu Diab’s register had $88,000 in EBT card transactions, according to WFTV.

This is the second time Abu Diab has faced the same charges, according to WFTV. The Daytona Beach News-Journal said he was accused of running a pawn shop without a license in December.
