New Jersey ? A 16-year-old boy who police said made an announcement at Walmart ordering all black people in a southern New Jersey store to leave was charged with harassment and bias intimidation, authorities said Saturday.

The boy, whose name is not being released because he is a juvenile, grabbed one of the courtesy phones at Walmart’s Washington Township store Sunday evening and calmly announced: “Attention, Walmart customers: All black people, leave the store now,” police said.

The teen was arrested Friday and released to the custody of his parents; police did not know whether he had a lawyer.

“This was an extremely disturbing event on many levels,” Gloucester County Prosecutor Sean Dalton said at a news conference. “Any statements like these that can cause harm or grave concern must be addressed as quickly as we possibly can.”
