Borough officers discovered the child after being called to the Boulevard apartment on a report of a youngster screaming for his parents just after 1 a.m. Monday, Detective Sgt. Kevin Van Saders said.
They arrested the 28-year-old father after catching him on the way back home and charged him with child endangerment, Van Saders said Tuesday.
They also turned the boy over to the state Department of Child Protection and Permanency, he said.
Charges were later downgraded.
