TV cook Nigella Lawson appeared to move out of her home after photos seemed to show her multi-millionaire husband grabbing her around the throat.
The self-styled domestic goddess was seen clutching a suitcase as she left the £12million Chelsea flat she shares with advertising tycoon Charles Saatchi.
She was then driven away in a blue taxi alongside her son Bruno, 17.
The 53-year-old and her husband were saying nothing about the incident but police confirmed they were looking into it.
