AKRON, Ohio (AP) -- Four people have been charged in a $2.2 million food stamp fraud investigation in northeast Ohio.

Authorities say the alleged fraud occurred over a three-year period at an Akron convenience store. State investigators and Summit County sheriff's deputies handled the case announced Wednesday.

The defendants are charged with counts including racketeering and receiving stolen property.

Twenty administrative charges also were filed against the convenience store, which could be fined or lose its state license for alleged drug dealing and other counts.

None of the defendants could be reached. No phone numbers were found for them.
