Police are appealing for witnesses after a 13-year-old boy was seriously injured this morning in a collision at Meadstead Drive in Royston, Barnsley.

A silver Vauxhall Astra is believed to have travelled down Manor Grove towards the junction with Meadstead Drive around 11.50am today, Saturday 23 July. It's thought the car went across the junction, through fencing, a garden and then through the front bedroom window of a bungalow.

A 13-year-old disabled boy was in the bedroom, sitting at a computer in his wheelchair. He became trapped underneath the car for at least an hour and had to be freed by firefighters. Police, doctors and paramedics were also at the scene.

The boy was airlifted to Sheffield Children's Hospital with a fractured right leg, where he's said to be in a stable condition.

The boy’s three siblings, a girl aged three and two boys aged five and eight, were also playing in the same room at the time. They suffered minor injuries and were taken to Barnsley District General Hospital but not detained.

The car driver, an 82-year-old local man, and his male passenger, also suffered minor injuries and were taken to BDGH.

Police are appealing for witnesses to the collision and to the manner of driving just prior to the crash. Anyone with information should contact South Yorkshire Police on 0114 2202020 quoting incident number 528 of today 23/7/11.
