The mother of another boy in that class disputes that claim, saying the student threatened her son.
"He decided to open up his book bag and he was like, 'look, I have bullets.' And he's showing the bullets off as if they were show and tell. My son, knowing the dangers of bullets, decided to walk away. And as he's going around, he hears them say 'well this bullet's got (her son's) name on it."
We are not identifying the mother or her son, who called Fox 5 News to report the incident.
"He's scared for his life at this point," she says of her 9-year-old son.
She says the other student was suspended for three days - the rest of last week.
"But as of Monday morning, he was returned into that same classroom with my son. And my son doesn't want to go to school."
Charles Co. school official Katie O'Malley-Simpson tells us no threats were made. "When the officer and staff investigated last week there was no mention of a threat."
And she says she cannot confirm how the student who brought the bullets to school was disciplined. "The possible punishment is suspension up to expulsion from school."
The mother who called us says the school's not taking the matter seriously enough.
"If he can get a hold of a bullet, he can get a hold of a gun. And it's not just my kid. When he gets bored with my son, who's he going to move on to?"
