This is the shocking moment a patient strapped to a stretcher fell out of the back of an ambulance.

Dashcam footage shows the back door fly open and the patient slide out of the vehicle onto the busy road in Bangkok, Thailand.

Paramedics inside then realised what had happened and retrieved the terrified patient.

Doctors later treated the man, who had originally been collected from a nearby motorcycle crash, and said that they did not find any additional injuries from the fall.

Theerawut Khampimabutr, head of the Poh Teck Tung voluntary foundation operating the ambulance, apologised for the incident and said that the team had been disciplined.

He said: "The careless paramedics had not cross-checked the equipment was secure before they started the ambulance's engine.

"Moreover, at that time many rescuers were involved with other cases which left only two people attending this accident, when normally we would have at least three.''

The spokesman for the rescue foundation apologised to the patient and promised to take full responsibility for the blunder.
