A man who fell out of a moving ambulance in Watford is now in a stable condition, a police watchdog has said.

The 46-year-old had been fighting for his life for the past week after falling out of the emergency vehicle which was travelling on the ring road by the town centre on Monday, April 12.

He was taken to a London hospital with serious injuries and had been critically ill.

The Independent Office for Police Conduct (IOPC) confirmed this morning (Tuesday, April 20) that the man is now in a stable condition.

The IOPC has launched an investigation into the incident as a police officer was with the man at the time he fell out of the ambulance last Monday.

Emergency services swarmed the area for several hours just after 10am, with several police cars and ambulances at the scene while an air ambulance was also called.

The IOPC’s investigation will look at the circumstances of the man's fall and the actions of the police in the lead up to the accident.

A spokesman from the watchdog added: "We sent investigators to the police post-incident procedures to begin gathering evidence and declared an independent investigation shortly after 1pm.

"We will be liaising with the man’s family to explain our role. So far we have taken initial accounts from the officers involved. We are also appealing for any witnesses to contact us."

The IOPC said there are no further updates regarding the investigation at this time.
