BURTONSVILLE, Md. - A teenager has been charged with bringing a handgun inside Paint Branch High School. He wasn’t a student, and he got in after providing a fake name and student identification number, Montgomery County Police said.

This is the second time in a week a weapon has made it onto school property.

In the most recent incident Tuesday, the school resource officer at Paint Branch High School learned about a teen who got away from the school after giving a fake name and ID number.

The SRO and a school security worker got a description of the teen and found him walking on Briggs Chaney Road at Columbia Pike. He tried to run away, police said, but they were able to arrest him.

He’s been identified as Elijah C. Nyamekye, a 17-year-old from Silver Spring.

Once in custody, the SRO searched a black shoulder bag Nyamekye was carrying and found a loaded .38 revolver inside. The revolver was reported as stolen in Pennsylvania, Montgomery County Police said.

Nyamekye has been charged as an adult with possession of a handgun, possession of a firearm by a person under 21 years old, possession of a stolen handgun, trespassing on school property and disruption school activities. Police are not releasing a mugshot of Nyamekye due to his age.

On June 7—just five days earlier—a student at the school brought a pocket knife and six rounds of handgun ammunition in a small, plastic sandwich bag. The 16-year-old was charged with possession of a dangerous weapon on school property and was released to his guardian. Police did not release the student’s name.
