The mother of a man who died in a motorcycle accident has appealed to whoever took the bike from the crash scene to hand it in to police.
Brett Roberts, 32, died in hospital on 7 August after the accident two days earlier in Leysdown, Isle of Sheppey.
Kent Police said the emergency services were called to the scene by an onlooker but the 125cc bike had disappeared by the time they arrived.
His mother said the bike could be dangerous and was needed as evidence.
Mr Roberts, who lived in London, is believed to have lost control of the bike before it crashed. He was not wearing a helmet.
"It is possible that the bike was defective, which could why Brett lost control of it," said his mother, Lenore, 50.
"However, even if it was in perfect condition and the accident was down to human error, the fact is that the bike has been involved in a collision and could very well be dangerous to drive now.
"I don't believe anyone is at fault for my son's death except himself, but now that bike could be a lethal weapon."
'Protect from harm'
Mr Roberts, who died in the Royal London Hospital, was a pool lifeguard in Greenwich.
He had been a frequent visitor to the Isle of Sheppey as a child and young man.
He was also a volunteer worker with drug and alcohol abusers in Greenwich and set up Narcotics Anonymous meetings at Elmley Prison, Isle of Sheppey.
He had two brothers aged 18 and 22 and a sister aged 23.
His mother, a lifelong motorcyclist herself, appealed to whoever took the bike to co-operate with police.
"They need to gather information for my son's inquest and protect the public from further harm," she said.
