Officers were called to Northwest Middle, at 5501 Murray Road, about 7:25 a.m. Monday after school officials were alerted that a student had a handgun in a classroom, police said. The student had the weapon in a book bag, according to investigators.

Police said there were no direct threats made to students or staff. However, juvenile charges will be sought in the case.

This came a day after threats were made on social media toward Reynolds High School, at 301 Hawthorne Road.

At least one of the threats was made on SnapChat and showed two guns and threatening language.

Police said in a news release Monday evening that they had identified the source of the disturbing posts and that the posts originated out of state. Local authorities are now working with law enforcement in that state, and the FBI, as they continue the investigation.

Police had additional officers at Reynolds on Monday and will have extra resources on campus as the investigation continues.

The district learned of the threat about 5:30 p.m Sunday, almost as soon as it appeared on social media and immediately notified law enforcement, said Brent Campbell, a spokesman for Winston-Salem/Forsyth County Schools.
