A construction worker heard the boy crying and recovered him. It is unclear how long the boy was at the site before he was found.

“That’s reckless endangerment,” another worker, Damian Stewart, told CBS2’s Marc Liverman. “You shouldn’t do that. That’s wickedness. You could give it up to adoption. You could call the police, drop it off at a fire station. You could even bring it to the hospital.”

The baby is in good condition and was taken to SUNY Downstate Medical Center for observation.

The Administration for Children’s Services was investigating the incident.
