The alleged incident took place last weekend at a Whole Foods Market in Edgewater, not far from a Wal-Mart in Gloucester County where a similar incident occurred last month.
Detective Lt. William Skidmore told The Record in Hackensack, N.J., the Whole Foods incident may have been a copycat stunt.
The 14-year-old teen was charged with bias and intimidation after store employees called police.
The Record reported Tuesday Whole Foods shoppers seemed to take the strange announcement in stride.
"I believe the reason there weren't any problems was because the store acted so prudently in calling right away, and the police response was so quick that anyone who was in the store saw these people get grabbed immediately and put in a police car," said Skidmore.
