A man yesterday admitted breaking his girlfriend's leg as part of a £100,000 insurance scam - by claiming a wall had fallen on her.
Reckless Gordon Thomson jumped on Elizabeth Hingston's limb in order to bring a civil action against Plymouth City Council.
Thomson, 32, intended to sue the authority by claiming his 23-year-old partner had broken her leg when a wall collapsed on her.
She agreed to take part in the scam and watched as her lover jumped onto her leg as the scene was filmed by a third party on a mobile phone.
The couple then tried to launch a civil action against the council by claiming the incident was the result of a public wall toppling onto her leg.
But they were caught when police raided his home and found a mobile phone video with 20 seconds of the incriminating footage.
Thomson pleaded guilty to unlawfully and maliciously causing grievous bodily harm with intent between October at Plymouth Crown Court, 1 and 30 last year.
Elizabeth Hingston - now his ex girlfriend - is not facing charges but a judge said she was "lucky not to be in court herself".
Bob Linford, mitigating, said the couple had hatched the plan to scam an undisclosed sum from the council.
He said: "This was a one-off incident which was caused by Elizabeth Hingston and him getting together and trying to inflict fraud on the local authority.
"The incident was taken on a mobile phone video. There is a victim in this case but she was a victim of her own making.
"A video clearly shows the act of violence and the cause of violence."
The court was told Thomson had previous psychiatric problems but Mr Linford said they were not an excuse for his actions.
He said: "Whatever problems he has, they are not anything to do with this offence.
"A psychiatrist has talked about a troubled past but none of the illnesses from which he suffers are causative of this behaviour."
Thomson, of Plymouth, Devon, was remanded in custody to appear at Plymouth Crown Court for sentencing on December 21.
Sentencing was adjourned for psychiatric reports but Judge Frances Gilbert warned him to expect a prison sentence.
He said: "In the light of the pleading guilty and in view of what I am told from medical reports, I adjourn for psychiatric reports as to whether you are to be regarded as dangerous offender.
"She is lucky she is not in court herself."
