Cyril Smith child abuse investigation 'was scrapped to protect powerful'
An undercover police operation that had gathered compelling evidence of child abuse by a prominent MP and a member of Britain's intelligence agencies was scrapped shortly after detectives moved in to make arrests, it was reported last night.
Police officers brought in the Liberal MP Sir Cyril Smith during an inquiry in the early 1980s which targeted properties in south London suspected of hosting sex parties involving teenage boys, but he was released within hours of being taken to a police station, according to information received by the BBC.
Officers were then ordered to hand over all of their evidence - including notebooks and video footage - and warned to keep quiet about the investigation or face prosecution under the Official Secrets Act.
The information was passed to the Newsnight programme by a former officer familiar with the original investigation and its closure.
Newsnight was informed of the intelligence-led operation, which it is believed began in 1981 and involved a team of undercover regional crime squad officers who were based at a large police headquarters in Kennington in south London.
The team targeted six or more addresses in south London, including a flat in a rundown tenement block around a mile from the House of Commons.
The squad believed that boys from care homes were being provided "to order" for sex parties.
Newsnight said it was told that during a three-month secret inquiry, officers gathered a substantial amount of evidence of men abusing boys aged around 14.
Evidence included photographs and video taken from inside a flat with a hidden camera.
Smith was seized at a property in Streatham where he had been taking part in a sex party with teenage boys.
It is understood he was taken to a police station but was released that night. A desk sergeant was reprimanded for wanting to keep him in custody.
The squad also had evidence relating to a member of Britain's intelligence agencies and two senior police officers.
Officers were assured those who had been caught "would not be playing a role in public life any more," but Smith continued as an MP until 1992.
He died in 2010.
