A 17-year-old Prince George’s County, Maryland, student has been charged after police say he brought a loaded gun and drugs to Fairmont Heights High School, authorities said.

Police said security personnel were tipped off that the student may have had drugs and when the student was searched, authorities discovered the gun, too. The gun had an attached machine conversion device, police said.

It happened shortly before 11 a.m. Wednesday, police said.

The 17-year-old will be charged as an adult with handgun on person, dangerous weapon on school property, possession of a firearm by a minor, loaded handgun on person, machine gun – aggressive purpose, rapid fire trigger activator violation as well as possession of a controlled substance.

WTOP has reached out to Prince George’s County Public Schools for a statement.

A similar incident occurred at Fairmont Heights High School last year when a student brought parts of a ghost gun into the school, which led to the school being on lockdown.
