Two audience members were injured when a stunt at an extreme motorsports show went wrong.
The Nitro Circus at Glasgow's SSE Hydro was temporarily halted on Thursday night when the volunteers were hurt during a biker's attempt to perform a backflip off a ramp.
Three audience volunteers were on the motorbike with a professional rider but it appeared to stall near the top of the ramp and tipped over the side.
One of the volunteers and the rider were able to walk away but two others were treated by medics at the scene before being taken to hospital suffering leg and facial injuries. All of those taking part were wearing helmets.
Video posted on social media showed the incident and the MC of the event said "that is the worst crash we have ever had".
The show was paused while workers and medical staff rushed to the scene and the MC added: "It's obviously not planned - occasionally something can go wrong. It's not meant to go wrong so we're taking a moment."
Nitro Circus, which describes itself as an action sports entertainment company, is currently touring across Europe.
The event is being staged at London's O2 on Saturday and Sunday before moving to Zurich and Paris.
One fan at the Glasgow show tweeted: ''Just at Nitro Circus in Glasgow. Hope the chaps on the four person backflip are ok! stretchered keep us updated!''
Another said: ''At nitro circus ssehydro. 4 man back flip just failed. Hope the members of the public ok.''
