A man decapitated himself on a Bronx street in a horrific suicide Monday morning.

Authorities say the 51-year-old man, who is from upstate New York, tied a metal chain around his neck and secured it to a pole at about 9:20 a.m in Hunts Point.

He then got into his car and accelerated, causing his head to be torn off.

The man's body was ejected from the car when he hit another parked vehicle, police told WPIX.

No criminality is suspected.
