An anti-corruption squad spent almost seven years trying to prosecute Detective Constable Dan Williams over allegedly running prostitutes on a sugar daddy website. The officer, 44, who has been suspended on full pay since his arrest in 2014, represented himself during multiple pre-trial hearings where he was able to reduce the charges and evidence prosecutors wanted to put before the jury in May. The final humiliation for the police came on March 2 when judge Michael Grieve QC excluded the main charge of misconduct in a public office by controlling prostitutes for gain as “unsustainable”.
The Crown Prosecution Service then announced it was “no longer in the public interest” to continue with the remaining lesser charges, and on March 8 Williams walked free.
It can now be disclosed the Met had also lost a legal bid to prevent Williams from airing explosive allegations of police corruption at his trial. The judge ruled that Williams could present a whistle-blowing defence to the jury and claim his prosecution was retaliation for speaking up about the “serious corruption and criminality” he claimed to have witnessed while serving on the Flying Squad, which investigates the most dangerous armed robbers.
Williams said between 2006 and 2011 senior officers turned a blind eye to violent criminals because they were valuable informants.
Judge Grieve’s ruling meant Williams could subpoena senior police officers and prosecutors to answer questions about specific Flying Squad operations detailed in the detective’s witness statement.
In it he claimed the Flying Squad had protected a prolific armed robber suspected of having a key role in major heists. He said the squad had refused to arrest him and kept his true role hidden from the court.
Criminal allegations Williams faced included taking a cut from the income of a 27-year-old sex worker.
It was alleged she had set up a vice ring with Williams while she was working as a part-time escort.
She was cleared of inciting prostitution for gain at Southwark Crown Court in January 2018.
Leaving court a free man, Williams joked that Cate Blanchett could play the prosecutor in a film of the case.
The detective, who joined the Met in 1997, is soon to retire on an ill health pension and will recover all his legal costs. The Met denied the failed prosecution, estimated to have cost £3million, was improper.
