MONTGOMERY COUNTY, Md. (FOX 5 DC) - UPDATE: Montgomery County Police say a 17-year-old student faces several charges for the shooting at Magruder High School Friday.
The incident occurred within a school bathroom around 12:30 p.m., police said at a press conference.
Once high school security became aware of the situation, they found a student had been shot and 911 was called at approximately 12:57 p.m.
The school went into a full lockdown moments later and the building was secured by MCPD.
During a search inside the school, officers found the suspect, Steven Alston Jr., in a classroom. He was taken into custody shortly after 3 p.m. and a privately manufactured gun, also known as a ghost gun, was found in the building.
While investigating the shooting, detectives determined the incident involved Alston Jr. and a 10th grade student, but add there is no evidence that Alston Jr. was targeting anyone else at the school.
Alston Jr. faces several charges including Attempted 2nd Degree Murder, 1st Degree Assault, and Possession of a Dangerous Weapon on School Property.
He is being charged as an adult, and will be held without bond.
Montgomery County Police say the victim was taken to an area hospital and is now listed in critical condition.
