A Baltimore high school student was arrested Thursday after bringing an unloaded handgun to Carver Vocational Technical High School, school officials said.
An investigation into the incident is under way, according to Edie House Foster, spokeswoman for Baltimore schools.
The school did not release the student's identity or information on how he or she obtained the gun, what charges the student faces or how the incident unfolded.
"The situation was under control promptly, without danger to any member of the school community," Foster said in an email. "Under the City Schools Student Code of Conduct, the student faces the maximum consequences, including possible permanent expulsion."
Baltimore City Public Schools Police, who took the student into custody, also notified Baltimore police, Foster said.
The incident is one of several in the region since the school year began in late August that has left many in the school community unnerved. Those earlier incidents took place in Baltimore County.
Earlier this month, a student brought bullets to Deer Park Middle Magnet after he and another boy, both 12, traded a Bersa .380-caliber gun for an Xbox 360.
A teacher at Stemmers Run Middle School in Essex wrestled a loaded handgun away from a 13-year-old boy in September.
While Baltimore County school resource officers were authorized this month to begin using hand-held metal detectors, Foster said all city schools have had access to metal detectors. Foster said the devices complement staff training, and bullying policies and procedures that guard against violence.
