A Scotland Yard whistleblower who claimed the Crown Prosecution Service is failing Asian female victims of honour crimes has been served a formal notice alleging gross misconduct for talking to the press by his employers at the Metropolitan Police.Det Sgt Pal Singh is facing possible disciplinary sanctions and even dismissal after disclosing to The Daily Telegraph that he believes “apathy” by prosecutors led to the collapse of what could have been the first conviction for forced marriage in England.He claims his treatment is “indicative of state censorship” and shows “public institutions are more concerned about their reputations than the victims of crime”. However, Det Sgt Singh, who received an excellent appraisal from his employer in May 2016 and has been commended three times in the past year for his work combating honour crimes, denies he has portrayed the MPS in a negative light or jeopardised any police investigation. He told The Daily Telegraph: “The article made the MPS appear to be diligent, competent and tenacious.” However, Det Sgt Singh claimed, the CPS “were furious about the article”. The Green Party’s Sian Berry, who sits on the Mayor’s police and crime committee, said: “This is a Met officer who worked hard on a lot of cases and noticed a pattern that concerned him. He raised a complaint to the CPS regarding this case and wasn’t satisfied with the response so went public about what he felt was part of a wider problem.”She added: “Whistleblower legislation is in place to protect people in exactly this way. It seems like an overreaction from the Met at a time when we need to be encouraging people to bring forward problems like this that need addressing.”A CPS spokesman said: “Any decisions about disciplinary proceedings would be a matter for the Metropolitan Police.”The Metropolitan Police confirmed it was investigating Det Sgt Singh for potential misconduct and refuted the claims made by him in his reaction to the notice. A spokesman said: “The MPS, like any organisation, expect its officers and staff to follow policies and procedures and investigate failures to do so.” In an article on Nov 8, 2016, he raised concerns that a “politically correct” CPS was failing to pursue convictions over honour crimes for fear of causing “unrest” in Asian communities. After the article appeared, the Attorney General, Jeremy Wright QC, made inquiries into the alleged failings by the CPS.His comments were supported by charities and Theresa May responded by insisting there was “no honour in so-called honour crimes”.Now Det Sgt Singh, who believes he should be protected by whistleblower legislation, has been informed he must attend a misconduct hearing.He told The Daily Telegraph: “Forced marriage is a violation of human rights, which invariably leads to marital rape and years of domestic abuse and modern slavery, with sometimes fatal consequences. If this is not a policing priority then I am content at being dismissed.” A notice served to Det Sgt Singh on Dec 8 deemed he dealt with the press “without seeking the relevant authority” and that his “comments may have had a detrimental effect on investigations”.
