A stuntman has sustained serious head injuries after reportedly falling on a film set at Warner Bros Studios.

Paramedics and an air ambulance were called to the Fast & Furious 9 set in Leavesden just before midday.

Production has been halted following the fall.

A spokeswoman for Universal said: "We had an injury on the set of Fast 9 today in Leavesden with one of our stuntmen.

"We have halted production for the day to focus on this situation."

A spokeswoman for Hertfordshire Constabulary said: "Police were called shortly before noon today following an incident at Warner Bros Studios in Leavesden, Hertfordshire.

"It was reported that a man had been injured while working at the location and sustained serious injuries.

"The air ambulance attended and police officers are currently on scene to assist and carry out initial enquiries."

The film stars franchise regulars Vin Diesel and Michelle Rodriguez, and is due for release in 2020.

It is the fourth time the studios has hit the headlines in just over a month.

A film worker sustained a small stab wound to the neck following an incident on the set of The Witches on June 19. Police confirmed the men were known to each other.

On July 11, up to 18 crews spent the day tackling a huge fire on the set of upcoming HBO series Avenue 5. A blaze broke out late on July 10 inside P Stage. No one was injured.

This week, it was revealed that police and the studios had launched an investigation after shards of glass and pins were found in muffins which were due to be sold at the cafes on the site.

The discovery was made on July 17 before any contaminated food was served to customers.
