A 16-year-old student wanted in a fatal shooting was busted with a loaded gun in his Harlem high school, cops said.
The allegedly pistol-packing teen was arrested Tuesday in A. Philip Randolph Campus High School, a landmark building with imposing spires on City College of New York’s campus, police said.
A school safety agent discovered the boy had a loaded gun inside a backpack, prompting NYPD cops to respond shortly after 12:50 p.m., according to police.

The boy — who was arrested on a gun charge — had also been wanted by the NYPD in connection with an April 17 shooting that left a 34-year-old Harlem man dead, cops said.
The teen terror had gotten into an argument with the man in NYCHA’s Manhattanville Houses along West 126th Street, police said.
With another person, the boy struck the older man with a closed fist, dropping him to the ground, officials said.

The youthful alleged miscreant then pulled a gun and shot the man in the chest, police said. Medics rushed the wounded man to Mount Sinai Morningside, where doctors pronounced him dead.
The teen was arraigned Wednesday on a slew of charges, including murder, manslaughter, assault with intent to cause serious injury and criminal possession of a weapon on school grounds, court records show.
He pleaded not guilty to the charges.
A judge ordered the boy to be held in jail without bail ahead of his next court appearance on May 6, the records show.
