Cops arrested a 14-year-old boy for bringing a loaded gun into his charter school in Brooklyn Friday morning, police said.

Shauquan Brown was allegedly caught just after 9 a.m. with a .22-caliber handgun with ammunition, after cops say his principal at Leadership Prep Charter School in Bedford-Stuyvesant received a tip that he was packing heat.

Brown was charged with criminal possession of a weapon on school grounds and criminal possession of a loaded weapon, and criminal possession of a defaced weapon, according to police.

Brown’s arrest comes just one day after another 14-year-old boy fired a gun on a loaded MTA bus in Brooklyn Thursday night, killing an innocent 39-year-old victim.
