A 17-year-old boy with a loaded handgun tucked inside his waistband was busted at his Brooklyn high school Monday morning, authorities said.
The teen was packing the loaded 9 mm handgun inside East Brooklyn High School on Kings Highway near East 96th Street in Flatbush just before 10 a.m., cops and sources said.
Another student spotted the firearm and quickly alerted teachers, who called 911, according to the sources.


The gun was recovered and the boy was taken into custody at the scene, with charges pending.
The school does not have metal detectors in place, but it is staffed by two school safety agents, sources said.
The incident comes just weeks after a 16-year-old student was busted with a loaded semiautomatic handgun at Benjamin Cardozo High School in Queens, police said.
He was arrested after disturbingly threatening to “shoot the school up” in an Instagram post flagged by the social media site’s moderators, cops and sources said.
