A New York teen was arrested after allegedly throwing a 9-year-old boy from the roof of their apartment building on Friday.

Freddy Martin is said to be clinging to life after police believe he was pushed from the roof of his family’s Bronx apartment building.

After the boy was found on the sidewalk outside the building screaming in pain for his mother at around 8:30 p.m., neighbors called 911. As Martin was being rushed to the hospital with severe body trauma, he reportedly told a police officer a teenager named Casmine Aska, 17, had thrown him off the roof.

The teen is believed to have dragged Martin from his family’s third-floor apartment and taken him to the roof. Though his grandmother was keeping an eye on him, she said she lost sight of him after he got up to get a drink after he had been laying down for awhile.

A neighbor later told police she heard the sounds of rough housing and even recalled hearing the younger boy yell, “Stop!” Thinking they were just “boys being boys” she thought nothing of it.

After being given Aska’s name by Martin, officers began looking for Aska at apartment building. Aska was confronted as he tried to slip out of the building with his brother and mother.

Aska was charged with attempted murder on Saturday. Police say his story has changed several times. After denying he was even on the roof he back tracked and admitted to being there. He then changed his story again, claiming he was on the roof and even tried to help as Martin fell.

According to the New York Daily News, Aska has four prior arrests that include robbery, assault, harassment, and menacing.

Martin’s father, Juan, has said his son is “not doing so well” but added the family is “holding out hope.”
