A man was stabbed to death after he flipped the bird to a group of people who had just gotten into an accident in the Bronx, police said.

The deadly incident began when the 25-year-old victim and two other men drove past the scene of a fender-bender in Eastchester, just before 6:45 p.m. Tuesday, officials said.

When someone shouted for their car to slow down, the victim gave the finger to the group, which was standing around one of the damaged cars.

Enraged, they hopped into their vehicle and chased down the victim’s ride, catching up with them near Hollers and Huguenot avenues.

The victim admitted he had given the finger and got out of the car to square off with the group before kicking their vehicle.

One of the men then stabbed him in the chest, police said.

The injured man’s friends started to drive the victim to a hospital before pulling over and calling 911.

Paramedics rushed him to Jacobi Medical Center, where he died.

His identity has not been released pending family notification.

Police found the knife at the scene of the stabbing.

No arrests have yet been made, police said.
