NYPD: Loaded firearm found in 17-year-old’s backpack inside NYC school

A 17-year-old is charged with possession of a weapon after bringing a loaded revolver to a Crown Heights school, police say.
This marks the fourth gun that has been found inside an New York City public school in the last two school weeks. School staff say they found the loaded revolver inside the student’s backpack this morning at Medgar Evers College Prep School. 
Sources tell News 12 that the high schooler smelled like marijuana and was stopped by the dean and school safety agents. He was taken to the dean’s office, when the loaded gun was allegedly found inside the backpack.  
The Department of Education said in a statement that school staff followed all of the appropriate protocols, and that weapons are not tolerated inside schools.  
Sources say the 17-year-old student had no prior criminal history and told school staffers that he had the gun for protection.
