A FOREST Hill sex attacker who was tracked down by police using a phone app has been jailed for six years.

Raymond Yates climbed through an open ground floor window of a Hurstbourne Road house in the early hours of July 25.

After taking off his shoes to conceal his approach, Yates climbed through the window, pinned a woman to her bed and sexually assaulted her, threatening to kill her if she made a sound.

He stole two mobile phones before fleeing and was later traced, using an app on one of the phones, to a bus in Brixton Hill just one hour after the attack.

Yates, of no fixed abode was found guilty of all sexual assault, trespass with intent to commit a sexual offence and robbery following a trial at Woolwich Crown Court on December 17.

And at Woolwich Crown Court on February 4 he was jailed for six year for the assault, along with concurrent sentences of six years for trespass and four years for the robbery.

Detective Chief Inspector Pete Thomas of the Met's Sexual Offences Exploitation and Child Abuse Command said: "The level of planning and thought Yates demonstrated while carrying out this offence shows he is a committed offender. While we have no concrete evidence of other offences we cannot discount the possibility that Yates may have carried out other attacks."

Anyone who believes they may have been a victim of Raymond Yates is asked to contact the Sapphire Unit on 020 8721 4678.
