Neighbors at the Forest Houses say they heard the mother screaming for help and that the child fell into an area that was under construction.
According to police, the child went tumbling through a space that is typically used to hold an air conditioner.
When police arrived, they say the boy was alert and he was taken to a hospital in Harlem.
Police say they do not expect the parents to face charges in this incident and it doesn't look like the fall was related to anything criminal at this time.
