Nigella Lawson faces police drugs investigation By Peter Wilkinson and Laura Smith-Spark, CNN December 22, 2013 -- Updated 1230 GMT (2030 HKT) UK police to examine evidence that celebrity chef Nigella Lawson took cocaine News came days after Lawson's two former assistants were cleared of fraud Both assistants claimed to have seen signs of repeated drug use by Lawson Lawson admits having occasionally used drugs including cocaine London (CNN) -- British police said Sunday they would examine evidence suggesting that celebrity chef Nigella Lawson took cocaine. The news came days after Lawson's two former personal assistants were cleared of fraud in a trial that saw the chef admit to occasionally using drugs including cocaine. In a statement on Sunday the Metropolitan Police said a specialist team would examine "all the evidence emerging as part of a review into this matter and in conjunction with the Crown Prosecution Service, will determine an appropriate way forward." However, police added that there was "no imminent prospect" of a prosecution being mounted against Lawson. The Senior Investigating Officer received legal advice that the witness's admissions did not by themselves provide sufficient evidence to bring charges. On Friday Lawson spoke out angrily against what she said were false claims of habitual drug use made against her in the trial of sisters Elisabetta and Francesca Grillo. Francesca Grillo had been accused of defrauding Lawson and her ex-husband Charles Saatchi of $950,000 (£580,000), and Elisabetta Grillo of defrauding them of $172,000 (£105,000). Both denied the charges. The case gripped UK media, thanks to revelations of drug use by Lawson and insights into her troubled marriage to Saatchi, a millionaire art collector. Lawson, who was a prosecution witness, said she was "disappointed but unsurprised" by the verdict. She slammed what she said was a sustained campaign to ruin her reputation. "Over the three week trial the jury was faced with a ridiculous sideshow of false allegations about drug use which made focus on the actual criminal trial impossible," Lawson said in a prepared statement.
