Tension which had been mounting between two couples over building works at a flat in Mayfair hit a high last October it has been announced, with an antique samurai sword being used as the couples finally came to blows.
Millionaire property developer Simon Carson was at the centre of attention as the troubles boiled over grabbing the antique weapon - worth thousands of pounds - and headed upstairs to confront Simon Korn after the estate agent had complained to a porter about the noise coming from downstairs.
Mr Korn, fearing for his safety, grabbed the sword and received series lacerations to his hands. Carson's wife Freddie Booker-Carson - an award winning art curator then slapped Mr Korn's wife and was abusive to police.
The dispute only emerged yesterday after Booker-Carson admitted assault and was given an absolute discharge at Southwark Crown Court.
Booker-Carson had been accused of 'assisting an offender' after hiding the sword in another of their flats but this charge was dropped after she said she hid the sword to prevent her husband 'self-harming'.
Carson was given a suspended sentence for actual bodily harm at an earlier hearing.
Simon Korn and his wife said that they were 'disgusted ' at the sentences, and that it appears to be one law for the rich and one for the poor.
