The child's moans and commotion drew many neighbors outside.
"He wasn't moving," said eyewitness Wanda Simonetti.
Police say the 9-year-old boy was thrown off from five stories above off of the roof of his building on Nelson Avenue in the Morris Heights Section of the Bronx by another man in the building, 17-year-old Casmine Aska.
Some neighbors say they overheard kids playing in the stairwell before the fall.
"I think they were up there; they all fell," said eyewitness Philip Rivera.
Sources say the nine-year-old victim told police Aska tossed him over the ledge. He has been charged with second degree attempted murder.
Investigators have not released a motive.
