Two people have been taken to hospital after a grandstand reportedly collapsed during a Trooping the Color rehearsal in central London.
Three others were treated at the scene by paramedics after the Horse Guards Road incident at about 11am on Saturday, the London Ambulance Service said.
the mirror reported that a woman fell through an opening in the stands, as did an eight-year-old boy named Ted Gibson.
According to the newspaper, his mother Clair Watts said: “We are very lucky and lucky that Ted was not seriously injured.
“Ted is absolutely obsessed with the guards and has been since he was a toddler.”
She described the incident and said they heard a scream as a woman fell through, adding that it was “confusion” in retrospect.
“The paramedics rushed in but started yelling ‘we can’t find her’.
“She was taken out after a few minutes and appeared to be okay but badly shaken and was put on a stretcher and loaded into an ambulance.
“The striking thing was that there seemed to be complete confusion among the police about what to do and where to find the victim under the stands.”
Dozens had turned up to watch the event, which is Major General’s review of the parade ahead of the full event on June 2 for the Queen’s Jubilee celebrations.
Witnesses said crowds were evacuated by emergency services and the ceremony, which includes a parade by the Household Division and Horse Guards, was aborted.
A spokesperson for the London Ambulance Service said: “We worked with volunteers from St John Ambulance to treat five people on site.
“We have taken one patient to a major trauma center as a matter of priority. St John Ambulance delivered a second priority patient to a major trauma center. We discharged three patients on the spot.”
One Twitter user wrote: “It was a fun experience to watch until we got up for the national anthem, the grandstand next to us collapsed with someone falling through.”
“They cut the procedure and the police started to evacuate us due to security concerns as there had already been 2 collapses for fear of more.
“It was certainly a very ‘British’ experience where we queued for an hour to watch horses and soldiers marching.”
Another witness told the PA news agency: “There was a loud bang, followed by a scream and a voice yelling ‘help, help’.
“A number of ambulances were on the scene and stretchers were used for the victims.”
Footage shared on Twitter showed people walking through the Horse Guards Parade away from empty stands.
A Defense Ministry spokesman said: “We are supporting emergency services following an incident in the Horse Guards parade ground.
“It would be inappropriate to comment further at this time.”
