NEW YORK (CBSNewYork) — Surveillance video captured a horrifying crash involving an ambulance and a car in Flatlands, Brooklyn, on Sunday afternoon.

The impact was so violent, the emergency vehicle overturned and was seen skidding on its side, CBS2’s Cory James reported.

One person was killed and eight others were injured, police said.

Yonelby Almanzar said the loud bang sent him racing out of his store.

“All you heard was a hard screech and the engine running and then all of a sudden you hear, doosh, car flips,” Almanzar said.

“It scared the hell out of me,” one woman said of the sound, adding, “and the ambulance automatically did a tumble sauce.”

Authorities said a black Nissan Maxima was traveling westbound on Avenue N while the ambulance was going southbound on Schenectady Avenue at around 3 p.m.

It is unclear if the ambulance had its siren on. Police are investigating which vehicle had the right of way.

Almanzar told CBS2’s Cory James people in the area rushed over to help seconds after the collision.

“Everybody was just helping each other out and trying to make sure everybody was good,” Almanzar said. “But you could see the ambulance workers just working their way out of the car and being helped by passersby.”

Police told CBS2 two people were in the car and a six-person crew was inside the ambulance, working on a 95-year-old woman who was in cardiac arrest. She was accompanied by her 67-year-old son.

Investigators said that woman died.

As police continue to investigate the deadly Easter Sunday collision, Almanzar said he doesn’t know who had the right of way, but what is clear is that, “Somebody must have hit the gas and wasn’t supposed to.”
