Scotland Yard officer investigated after sending 'inappropriate text' to millionaire's daughter Laura Johnson The matter is now being investigated by the Directorate of Professional Standards, the Met's internal investigations unit, and will be reviewed by Judge Patricia Lees, who presided over the three week trial. DC Quigley, who is an expert on gangs, gave evidence for the prosecution in the trial. He told the court what Johnson had said about possible gang links of her looting 'companions'. DC Quigley visited her home in Orpington, Kent after the family complained that pictures taken of their house and published in the press could tip off south London gangsters where they lived. The family had also claimed to have received anonymous letters which they believed were sent by gangs to try and intimidate Johnson before her trial. A Met Police spokesman refused to comment on the case while investigations were ongoing.
