A Bronx student stabbed a classmate to death with a pair of scissors and seriously injured another inside their high school Wednesday morning — and cops are investigating if bullying was a motive, sources said.
Investigators believe an 18-year-old plunged the tool into a 15- and 16-year-old around 10:50 a.m. on the fifth floor of the Urban Assembly School for Wildlife Conservation on Mohegan Avenue in East Tremont, sources said.
The motive was not immediately clear, but investigators believe the attacker may have been the target of repeated bullying, the sources said.
The 15-year-old, who was stabbed in the chest, was pronounced dead on arrival at St. Barnabas Hospital and the 16-year-old was fighting for his life there, sources said.
The 18-year-old was arrested and was being held at the 48th Precinct, though charges have not been issued, sources said.
The school, which does not have metal detectors, serves sixth through 12th grades and is co-located with elementary school PS 67.
The campus is a low performer and kids have told the city they do not feel safe there.
Just 5 percent of pupils there are proficient in math and 13 percent in English, according to last year’s state exam results. And less than half of students polled at the school last year — 47 percent — said they felt safe on campus, well below the city average.
Mayor Bill de Blasio is “likely to make an appearance in the Bronx later this afternoon,” spokesman Eric Phillips tweeted.
