Casmine Aska, 17, was ordered held without bail Sunday.

The twisted teen accused of pushing his 9-year-old neighbor off the roof of their five-story Bronx apartment building told cops it was an accident — but admitted he didn’t go for help.

“I grabbed Freddy around the legs,” Casmine Aska, 17, said, referring to victim Freddy Martin, according to court papers.

“His feet were off the ground. I turned around. I slipped and Freddy fell. I did not call 911. I did not tell my mother. I did not check to see if Freddy was okay.”

Bizarrely, Aska said, “I did not hear the thud until I went into the apartment.”
