A BAREFOOT criminal who robbed and sexually assaulted a 23-year-old woman after breaking into her Forest Hill home was found guilty yesterday (December 17) after police used a phone app to track him down.

Raymond Yates, 31, of no fixed abode, climbed through an open ground floor window of the victim's address in Hurstbourne Road, Forest Hill, in the early hours of July 25 to carry out a “harrowing attack”.

CCTV shows Yates looking in the window of the property before wrapping a t-shirt around his face to conceal his identity.

He wore no shoes to reduce the chances of him being heard as he approached the window.

The victim, who was asleep in that room, awoke to find Yates straddling her and pinning her to her bed.

He then sexually assaulted the woman and threatened to kill her if she made a sound. He then fled through the same window having stolen two mobile phones. The attack lasted around a minute.

Officers traced Yates using an app on one of the stolen mobile phones and he was arrested on board a bus in Brixton Hill around an hour after the incident at 6am.

Raymond Yates, was convicted of robbery, sexual assault and trespass with intent to commit a sexual offence following a trial at Woolwich Crown Court. He will be sentenced on January 28.

Detective Constable Corrado Di Mascio of the Met's Sapphire Unit said: “"This was a particularly harrowing attack on a lone woman while she slept in her bed at home.

"The evidence shows Yates was calculating in his attack, concealing his identity and taking off his shoes in an attempt to mask his approach.

"I would like to praise the victim who has been committed to seeing her attacker brought to justice."

Saphire’s Detective Chief Inspector Pete Thomas said: “While we have no concrete evidence of other offences we cannot discount the possibility Yates may have carried out other attacks.”

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