Detectives investigating an alleged historical Westminster paedophile ring are also investigating the murder of three boys.
Scotland Yard said on Thursday it was appealing for evidence as inquiries centred on Dolphin Square estate, in central London, and other locations across London and the south of England, including military establishments.
Detectives said they believed a witness who said he was abused by the VIP sex ring.
Det Supt Ken McDonald, head of the inquiry, said of the witness called Nick: “I believe what Nick saying is credible and true”.
