Three weeks after the Virginia school where a 6-year-old shot his teacher reopened, a fifth-grade student made threats to “pop some bullets,” a school spokesperson said Tuesday.

In a letter to families and the Richneck Elementary School community in Newport News, Virginia, an administrator said a fifth-grader in a group text conversation with other students over the weekend said they would “pop some bullets” and tell someone to shoot up a class. 

“I immediately contacted the student’s parent and excluded the student from school,” Karen Lynch, an administrator on special assignment to lead Richneck, said in the message.

WHO COMMITS GUN VIOLENCE IN AMERICA?:A child shot his teacher, a 72-year-old man opened fire in public: Here’s what that tells us about guns in America.

The letter, shared with USA TODAY by district spokesperson Michelle Price, comes after a first-grader shot and severely injured his teacher, Abigail Zwerner, on Jan. 6.

Zwerner’s attorney declined to comment on the fifth-grader who made threats. Attorneys for Zwerner, whose injuries were considered life-threatening but who has since left the hospital and is recovering, said they intend to file a lawsuit on her behalf against Newport News Public Schools.

WHAT WE KNOW:Where did the 6-year-old get the gun? Will anyone be charged with a crime?

The attorneys alleged that school administrators were warned repeatedly the day of the shooting that the child may have had a gun on him.

The gun was legally purchased by the boy’s mother, police said. An attorney for the child’s family said the gun was stored with a trigger lock on the top shelf of a closet and the family does not know how he got it. No charges have been filed in the case.
