At around 3:30 p.m., a resident of the building tipped off police, saying that a boy was found collapsed and bleeding from his head on the grounds after a loud sound.
The boy, 15, was transported in a state of cardiac arrest to a hospital where he was later confirmed dead, according to police.
The boy did not live in the building. His backpack containing his student identification card was found on a ninth-floor stairwell, police said.
Police are now investigating the circumstances that led to the boy plunging from the building in a case as that is being treated as the result of an accident, foul play or suicide.
