Two members of the public have been injured as they were taking part in a motorbike backflip stunt at the Nitro Circus motorsports show.

Audience members at the show in Glasgow's Hydro Arena said the stunt involved three volunteers and a motorcycle stunt rider who were to backflip off a ramp.

However the stunt went wrong, leading to the vehicle and all four people falling off the ramp.

It is understood two members of the public have been taken to hospital, one with injuries to their hip and another with injuries to their face.

After the incident there was a break in the show, and the announcer told the audience: "Obviously what happened at the end of that first half, definitely not planned. It does happen from time to time, I've never seen it happen like that."

He said the two injured people were "having a laugh, in good spirits" and were on their way to hospital. One had "taken a bike to the face," he said.

The show's announcer added: "I knew Glasgow was tough, but you have definitely proved you can take the worst hit in Nitro Circus history and have a bloody good laugh about it."

A spokesman for Nitro Circus said: "During Thursday night's Nitro Circus Live show at Glasgow’s SSE Hydro Arena, two passengers who sustained injuries during a four-person motorbike backflip attempt were transported to a nearby hospital.

"One is fine apart from some bruises. The other has a broken jaw and will have surgery on Friday, but is in good spirits and is expected to make a full recovery.

"Nitro Circus considers health and safety its top priority and has expert medical staff on site in the event of an emergency. Nitro Circus will make no further comment regarding this matter."

The Scottish Ambulance Service said they had taken one person to hospital with a hip injury, and another was taken to hospital by private ambulance.
