A PREDATORY sex offender locked away in 2008 has pleaded guilty to two further rape charges and three counts of attempted trespass to commit a sexual offence.

Keith Fenton, formerly of Osterley Park Road, Southall, was sentenced to 15 years' imprisonment and handed an Indefinite Public Protection Sentence in November 2008 for serious sexual assaults, false imprisonment and aggravated burglary.

But, the 38-year-old was suspected of committing further offences and was hauled to Kingston Crown Court on Friday July 19 where he confessed he had befriended a vulnerable woman and raped her twice at her Ealing address.

The court heard how he had taken a form of Viagra, cut her clothing from her as she lay almost unconscious from alcohol and raped her twice between March 6 and June 22 2008.

Fenton further told the court that on May 16 2008, he attempted to break into a property in Ruskin Avenue, Kew, with a screwdriver in order to rape a woman at knife point.

Between March 6 and June 22 of the same year, he attempted to pick the putty away from a window at a property in Defoe Avenue, Kew, in order to break into the home.

The third offence during the same time was at a property in Strand Drive, Kew, where he climbed up a lightning conductor on a building and attempted to enter the house through an open window.

On all three occasions, he fled after being disturbed and officers from Richmond Borough Violent and Sexual Crime Unit later approached the victims to disclose the offences to them.

CPS London lawyer Roz Wardell said: "Although already serving a significant prison sentence the Crown Prosecution Service concluded that this case was in the public interest to proceed with. It's important for the victims of the offences to see justice done and for the scale of Keith Fenton's criminality to be recorded.

The CPS worked with the police from a very early stage in order to establish the veracity of Fenton's claims and ensure those who may not have realised they were targeted by him were not alarmed unduly by his claims.

"Keith Fenton is a predatory serial sex offender and these further convictions will ensure he is not allowed back into society for a long time."

He will return to Kingston Crown Court on September 24 to be sentenced.
