A mentally ill man jumped to his death from the Trump International Hotel and Tower near Central Park Sunday morning, police said.

The 41-year-old man was witnessed jumping from the roof of the building, located on Central Park West and West 61st Street, around 6 a.m.

His body landed in the building’s front courtyard, not far from the sidewalk.

Police sources said the man died at the scene.

Just before taking the fatal leap, the man’s 67-year-old mother, who lives in the building with him, called 911 to say that her son was schizophrenic, on drugs and planned to kill himself.
