(WSB Radio)  Hundreds of metro Atlanta residents are upset after they get home and find out what they thought was a video game they purchased is a blank disc.

Now, Carrollton Police say they've broken up a huge theft ring responsible for all the anger.

Police say the suspects in the ring bought the games, then returned them to several Wal-Marts, including ones in Woodstock and Marietta.  The crooks would take out the game disc and replace it with a blank one, then return the case to the stores.  

Security Consultant Brent Brown tells Channel 2 Action News Wal-Mart won't tolerate this.

"Wal-Mart is big enough that they do it right.  They have to.  If they don't,  they could be taken down by petty crimes that get bigger and bigger,"  he says.

Up to $10,000 worth of merchandise has been stolen, but it could be more since the ring is believed to have started in February.

Police have arrested the suspected ringleader, 29-year-old Lavar Thornton.  Two University of West Georgia students, Tyrell Myers and Michael Cunningham, have also been arrested.
