One of the horses that pulls carriages around Central Park died Friday after breaking loose and running into a tree, police said. No people were injured.

Witnesses said the horse, which became startled by a street performer playing a drum, ran nearly a block along the sidewalk on the southern edge of the park before colliding with the tree, said Joseph Pentangelo, assistant director of the American Society for the Prevention of Cruelty to Animals.

The 13-year-old animal, named Smoothie, had been a carriage horse for only a year, an official said.

“We are devastated by the tragic and sudden loss of our mare Smoothie,” said Carolyn Daly, a spokeswoman for the Horse & Carriage Association of New York. “This afternoon’s freak accident was overwhelming to all of us in the industry who so dearly love our horses
