The Sunday People newspaper ran pictures of what it said was the couple's violent argument at a London restaurant on June 9.
Saatchi, Britain's best-known art collector, told London Evening Standard newspaper on Monday that the pictures misrepresented a ``playful tiff.''
Saatchi, a columnist for the London Evening Standard, said ``the pictures are horrific but give a far more drastic and violent impression of what took place.''
Lawson's spokesman, Mark Hutchinson, declined to comment.
London police say it has received no criminal complaint, and ``inquiries are in hand to establish the facts'' in order to assess whether a formal investigation is necessary.
