An 11-year-old special needs student was suspended from a New Jersey elementary school for possession of a "Nerf bullet."

According to the Atlantic City school district, fifth grader Aarin Moody's foam dart, which had a toothpick embedded in the tip, resembled a makeshift knife.

"It's a toy with a toothpick on it," the boy's mother, Michelle Moody, told CBS.

Aarin, who accidentally left the Nerf bullet in his pocket, says the toothpick allowed him to make the dart stick in the dirt.

"I pulled out my late slip and that's when the item fell out of my pocket and a teacher had seen it," Aarin said.

Michelle received a call from the school's vice principal shortly after and was informed that her son, who had been taken to the office by a security guard, would be expelled for possessing a self constructed weapon "capable of lethal use or inflicting serious bodily injury."
