On Sunday evening at the Washington Township store, a male voice calmly announced: “Attention Wal-Mart customers: All black people leave the store now.”

Witnesses told the Courier-Post newspaper that customers and store employees looked stunned.

Management later apologized. Company spokeswoman Ashley Hardie says the incident was “unacceptable.”

The retailer is looking to prevent it from happening in the future. Washington Township police and the Gloucester County Prosecutor's Office also are investigating.
