46-year-old Cesar Arana-Oliveras of Yonkers is charged with endangering the welfare of a child.
White Plains Public Safety Commissioner David Chong says Arana-Oliveras grabbed a 3-year-old off the porch of a house on Bryant Avenue in White Plains.
Chong says the suspect didn't belong in the area, was wearing a Halloween mask, and was trick-or-treating without any kids.
Arana-Oliveras told police he did it as a prank, not as any kind of crime. But authorities are continuing to investigate the incident.
