An ambulance carrying a patient and three attendants lost control and crashed into a toll booth in Karnataka's Udupi district, killing four people including the patient. A CCTV camera at the toll booth shows the horrific accident. In the footage the ambulance was almost at the toll plaza when one of the operators manages to pull out the last barricade. But by then the ambulance tyres lost traction, skidded off the road and crashed into the toll booth cabin. Watch this video to know more.
