Scotland Yard is seeking "to establish the facts" of an apparent violent row between the television chef Nigella Lawson and her husband Charles Saatchi during which he placed his hand around her throat.
The multi-millionaire art collector and his wife were photographed at their table outside the famous Scott's seafood restaurant in Mayfair eight days ago on Saatchi's 70th birthday during a seemingly bitter argument which left Lawson in tears.
The pictures, published by British newspaper the Sunday People showed former advertising guru Saatchi putting his hand around Lawson's neck four times, on one occasion raising a second hand towards her throat and on another seeming to grip or pinch her nose
The couple left their home in London's Chelsea in separate taxis on Sunday morning. Both remained stony-faced and said nothing about the photographs, which were published on the Sunday tabloid's front page and generated substantial comment on Twitter.
In a statement, the Metropolitan Police said it had not received a complaint about the incident two Sundays ago but was looking into it following the newspaper article. The Yard said: "Officers from the Community Safety Unit at Westminster are aware of the Sunday People article. Enquiries are in hand to establish the facts of the incident."
