A schoolboy who broke his arm while using a trampoline in a new playground in South Kilburn is warning others about the risks..

Jack Martin Baxter, who lives in Alpha Place with his grandparents, was bouncing on a trampoline in Woodhouse Urban Park, Albert Road, when he broke his arm in two places..

The 15-year-old, who spent four days in hospital and is still in pain, said: “The trampoline is really small so it’s survival of the fittest of who can get there first. There were eight children near it all trying to rush on to it but I got to it first and went to bounce on it. When I sprung up I saw another kid was in my way so tried to jump over him to get off but as I did, my knee clipped his shoulder, I fell and landed on my hand. I only knew how bad it was when I saw my bone jutting out my arm. It was a big shock to me.”

The Queens Park Community School pupil, who now has to miss out on work experience for a football club, added: “It’s a new park and the kids love it. I don’t want to be the reason to get rid of the trampoline but because of what was done to me I need to be the first and the last person to get injured. It’s proper scared me.”

The park, part of the South Kilburn regeneration project, was officially opened in May.

Jack’s grandmother Barbara Joyce, said: “He’s finally home now but in agony. It could have been worse, if he’d landed on his head he might be dead.

“It’s the danger of it, I’m so worried for other kids, something should be done to get rid of it.”

A council spokeswoman said: “We are sorry to hear that Jack hurt himself in the park. We’ve not heard about any other incidents involving the trampoline at Woodhouse - and we have the same equipment being used elsewhere, without any problems.

“Our playgrounds are all provided and installed to stringent safety standards, and inspected twice a week to ensure their ongoing safety.”
