British detectives examining accusations of historical sexual abuse have launched a new investigation into "possible homicide".
Scotland Yard said officers from Operation Fairbank, which is looking into claims there was a paedophile ring with links to government, have received allegations concerning "serious non-recent sexual abuse", said to have taken place more than 30 years ago.
A spokesman said: "Our enquiries 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 (police)."
"Detectives from the Child Abuse Investigation Command are working closely with colleagues from the Homicide and Major Crime Command concerning this information."
The new investigation has been titled Operation Midland.
Operation Fairbank was launched in response to information from an MP, Tom Watson, who used Prime Minister's Questions in 2012 to raise allegations that there was a paedophile ring with links to Downing Street.
He invoked parliamentary privilege to allege that a file of evidence used to convict Peter Righton of importing child pornography in 1992 contained "clear intelligence" of the ring.
The allegations have triggered to more inquiries: Fairbank, which is investigating claims linked to the Elm Guest House in Barnes, south west London in the 1980s, and Cayacos, which is investigating claims of a paedophile ring linked to Righton.
In August, Scotland Yard said it had tripled the number of officers investigating the allegations of sex abuse. Met Police Commissioner Sir Bernard Hogan-Howe said staffing was now "well over 20".
He said: "We've tripled the number of people in there this week. Well over 20 people will be dedicated to that and we will make an assessment of the cases. It takes a little while because sometimes victims will have moved on to other parts of the country, sometimes abroad, and that poses its own challenges."
"Not all the people are prepared to tell us all the details or to go on to the criminal justice process."
Reporter Martin Brunt has been looking at the new development.
