Two ambulances crashed in an intersection on Saturday and four EMS workers were injured, the FDNY said.
One civilian was also cut by glass while trying to help, firefighters said, but that person refused to go to the hospital.
The ambulances were both responding to the same request for backup just two blocks away from the crash, the FDNY said. Both had lights and sirens on.
Surveillance video shows both ambulances entering the intersection when one T-bones the other. The ambulance that overturned was thrown into a traffic light, knocking it down.
The ambulances crashed at Brook Avenue and 142nd Street in the Mott Haven neighborhood just after 2 p.m., the FDNY said.
