'Homicide' probe into child abuse
Detectives examining allegations of historic sex abuse with links to government have launched a new investigation into "possible homicide".
Scotland Yard said Operation Midland was started after officers working on Operation Fairbank, which is looking into claims of "serious non-recent sexual abuse", were given information about alleged murders.
A spokesman said: "Our inquiries into this, over subsequent weeks, have revealed further information regarding possible homicide. Based on our current knowledge, this is the first time that this specific information has been passed to the Met."
The BBC quoted a man who, it claimed, has told police investigating the alleged abuse that "former senior military and political figures", as well as "law enforcement", were involved.
According to the broadcaster, the witness, now in his 40s, claimed the group had access to 15 to 20 youngsters.
The man, who was speaking anonymously, said: "It started with my father. It started with quite severe physical abuse, quickly turning into sexual as well.
"Within a very short space of time he had handed me over, or whatever you want to call it, to the group. They controlled my life for the next nine years.
"They created fear that penetrated every part of me. That was part of my life, day in and day out. You didn't question what they wanted, you didn't hesitate to do what they asked you to do.
"You did what you were told without question or the punishments were very severe. They had no hesitation in doing what they wanted to do.
"Some of them were quite open about who they were. They had no fear at all of being caught, it didn't even cross their mind. They could do anything they wanted without question and we were told that.
"I've never experienced pain like it and I hope I never do again."
Scotland Yard said: " At this early stage in this inquiry, with much work still to do, it is not appropriate to issue appeals or reveal more information.
"Detectives from the child abuse investigation command are working closely with colleagues from the homicide and major crime command concerning this information, which is being looked at under the name of Operation Midland."
Operation Fairbank was launched in response to information passed on by MP Tom Watson, who used Prime Minister's Questions in 2012 to air claims that there was a paedophile ring with links to No 10.
Mr Watson used parliamentary privilege to allege that a file of evidence used to convict Peter Righton of importing child pornography in 1992 contained ''clear intelligence'' of a sex abuse gang.
He wrote to Scotland Yard, which has since spawned two more inquiries from Fairbank - Fernbridge, which is looking at claims linked to the Elm Guest House in Barnes, south west London, in the 1980s, and Cayacos.
In August, Scotland Yard said it had tripled the number of officers investigating the allegations of sex abuse in the wake of the claims of a Westminster cover-up.
The anonymous witness quoted by the BBC urged people to come forward with information. He said: "Anyone who knew anything, it's important they come forward too. They need to find the strength that we as survivors have done.
"If they have any suspicions, if they have any concerns, if they know they were part of it, they need to come forward and share what they know.
"People who drove us around could come forward. Staff in some of the locations could come forward. There are so many people who must have had suspicions. We weren't smuggled in under a blanket through the back door. It was done openly and people must've questioned that. They need to come forward."
