NEW YORK (AP) — Police say a man involved in a custody dispute apparently threw his 3-year-old son off the roof of a 52-story Manhattan apartment building before jumping to his death.

Police say they received an emergency call reporting two jumpers from the building around noon Sunday. Officers found 35-year-old Dmitriy Kanarikov and his son on the lower rooftops of two nearby buildings.

The Brooklyn man was pronounced dead at the scene and his son, Kirill Kanarikov, was pronounced dead at a local hospital.

Officials say the boy's mother had custody of the child. They say that the father had visiting rights and was supposed to hand the boy over to the mother at a police precinct Sunday afternoon.

Police say the father did not live in the Upper West Side building listed as South Park Tower. The building is a short distance away from Columbus Circle and Lincoln Center.
