A man has died of catastrophic brain injury after stealing a motorbike and then crashing it into a traffic sign in Rotherham, an investigation has found.
Wayne Kershaw, 40, died at Sheffield Northern General Hospital on August 12, 2020, three days after the serious accident on Rotherham Road.
A passing taxi driver found Mr Kershaw and the Yamaha motorcycle by the side of the road under a metal sign and called 999 at around 1:45 am on Sunday August 9.
But despite the best efforts of medical staff, his injuries proved insurmountable and support was withdrawn on August 12.

Senior Coroner Nicola Mundy continued an inquest into his death in Doncaster Coroners Court on Thursday, which learned that Mr Kershaw had extremely high levels of amphetamine in his system while riding the motorcycle.
A toxicology report read in court noted that the drug levels in his system were between toxic and deadly ranges.
The report stated: “The drug level would have seriously impaired his ability to ride a motorcycle.
“It would have made him more likely to get out of his lane, accelerate and drive more aggressively and violently.”
In a statement from his partner read to court, it was said that Mr Kershaw received an early morning text message from a friend asking him to come out and “do a job”.

She said Mr. Kershaw had never owned a motorcycle or was interested in it as far as she knew.
PC Paula Townsend told the inquest that Mr Kershaw and a friend stole two motorcycles from a business premises on Erskine Road.
She also said it was no more than a mile or two from the crash site from where the bikes were stolen.
The officer also said his driver’s license had expired and he had no insurance for the motorcycle.
Forensic investigator Andrew Oglesby told court the crash happened just 32m after the railway bridge where the bicycle tire could be seen hitting the sidewalk.
In his testimony he testified that there was no evidence of emergency braking or evasive action to prevent Mr. Kershaw from hitting the metal panel.
It was also understood that he was not wearing protective clothing, including a helmet, at the time of the crash.
He said: “There is a strong possibility, almost a certainty, that Mr. Kershaw was traveling over the 30 mph speed limit the moment he left the road surface.”
He also added that the motorcycle he was riding was “not a beginner’s motorcycle” and was a “handful” to ride.
