Four people have been taken to hospital and scores more injured at a Christmas lights switch-on.
As X Factor runners-up JLS took to the stage in Birmingham city centre, a metal barrier penning the crowd in collapsed, leaving 60 people needing treatment, said West Midlands Ambulance Service.
The planned concert and lights switch-on were cancelled as paramedics set up a special unit to treat the wounded.
According to reports, thousands more than the 5,000 fans expected turned up at Saturday's event.
JLS were due to perform alongside the Sugababes but the event was hastily cancelled.
One woman in her 30s suffered serious crush injuries to her pelvis, shoulder and leg. Another woman broke her ankle in the surge, which happened at Millennium Point on Jennens Lane at about 1.30pm.
A teenage boy fractured his wrist, while a girl in her teens suffered crush injuries to her back and legs.
A ambulance service spokeswoman said: "The remaining 56 patients suffered minor crush injuries and a range of minor medical complaints. They did not require further hospital treatment and were all discharged by ambulance crews at the scene."
