The Met Police paedophile unit is now  investigating the sadistic murder of a boy  possibly by one of the country’s most notorious paedophiles Sidney Cooke.

The allegations have surfaced as part of a renewed investigation into sex abuse parties held in the 1980s following the seizure of film  by the Met Police in their investigation into whether there was a  group of VIP paedophiles, including a former Cabinet minister, in the 1980s.

 Details are revealed by my colleague Mark Conrad on the Exaro website this weekend.

 He writes: “Police believe that some of the “sex parties” were organised by Sidney Cooke, the notorious paedophile who led the ring of four who were jailed for killing Jason Swift, a 14-year-old boy, in Hackney, east London after gang raping him in 1984.

In a chilling development, the detectives are investigating whether Cooke was involved in an incident in which a pre-teen boy was strangled to death during a sustained sexual attack at a basement flat in London.

Detectives have interviewed what they believe to be a witness to the murder.”

 Cooke is still serving a life sentence in jail for the sexual abuse of two young brothers in the 1970s and 1980s and is now aged 86, one of the growing numbers of elderly paedophiles in prison following successful police prosecutions.

In a quite separate and bizarre development allegations are being made that the security services and special branch may be involved in monitoring the revival of investigations into paedophile rings in the 1980s. People have turned up at  survivors and witnesses addresses saying they are journalists but leaving no cards or numbers. in the latest development reported in the Sunday People and Exaro News a person turned up at a key witness address saying he was from the Sunday People  They had not sent anyone there.

This is disturbing given the alleged record of the security services and special branch about Cyril Smith – who had been monitored by special branch – but no criminal action was taken against him. It could be that the security services are becoming the insecurity services as a result of these new investigations.
