A toddler who plummeted 15ft from a window at his Pudsey home suffered "irrecoverable" injuries to his brain, an inquest was told.

Two-year-old Mohammed Raees Khan died in Leeds General Infirmary on September 7 after the fall at his home in Daleside Close.

Coroner David Hinchliffe told the hearing at Leeds Coroner's Court that Raees had been playing with his brother and sisters when his brother had opened a large first floor window. When his ten-year-old sister entered the room, Raees was standing on the windowsill laughing. As she approached to take him down, he stepped backwards and fell on to concrete below.

Raees's mother, Najma Karim found Raees unconscious on the path with blood coming from his nose. He was taken to hospital.

Mr Khan, of Bradford, told the hearing that staff at both Bradford Royal Infirmary and Leeds General Infirm-ary informed him Raees had suffered only light bruising to the brain and lungs and would make a full recovery.

He said he believed these then turned into serious problems when he was being treated at Leeds General Infirmary when a ventilator cut out.

"Raees was connected up and it was while adjustments were being made that the machinery was switched off accidentally," said Mr Khan. "I was there and I saw it. The staff there didn't know what they were doing. They didn't know where it switched off and were trying to switch it back on."

Dr Tim Haywood, a consultant in the paediatric intensive care unit at Leeds General Infirmary said when Raees was being transferred to a high dependency ventilator, it automatically cut out several times. During this time, Raees was hand-ventilated. He said the machine was "perfectly functioning" and the problem had been caused by water being directed into the machine which had upset the electronics.

Dr Susan Clayton, the consultant forensic pathologist who carried out a post-mortem examination on Raees, said he had died from a multi-organ failure caused by a brain injury and skull fracture. She said the hairline fracture to his skull was so small, she could not see it on x-rays.

"His brain injury was severe and was unrecoverable," said Dr Clayton. "I could see no signs of healing - everything appeared to be getting worse."
