George Wallace, 26 of Wichling Close, Orpington, was found guilty of attempted rape and trespass with intent to commit a sexual offence at Woolwich Crown Court following a trial on Monday, 23 November.
He was sentenced on the same day to a total of nine years’ imprisonment – and will have to serve at least two thirds of his sentence before being considered for release. He will then spend an additional five years on licence.
He has also been put on the sex offenders register for life.
Wallace grabbed the victim, exposed himself and attempted to rape her.
Wallace made his way out of the flat via the bathroom window.
Wallace was identified through fingerprints found on the bathroom window where he had entered and exited the flat. A vodka bottle was also found left in the flat, on which the DNA of Wallace was later discovered.
Detective Constable Paul Harakis, of the Met’s South Area Safeguarding team, said: “The fingerprint and DNA evidence in this investigation was vital in identifying Wallace. It highlights the good proactive work we do to ensure offenders are identified and brought to justice.
“I hope that the verdict and sentencing brings the victim some level of closure. We take these cases very seriously and I would encourage anyone who has been through a similar experience to come forward and report it to us in confidence.”
