A teenager who raped a woman at knifepoint in broad daylight in an Eltham park has had his jail sentence increased because the original sentence was not considered strong enough.

The teenager from Lee Green, who cannot be named due to his age, was 15 at the time when he targeted the 46-year-old victim in Sutcliffe Park.

She was walking in the park on April 19 last year when the teenager threatened her with a knife, put an arm around her and told her to "act normal" and threatened to stab her in the face if she tried to run away.

When the woman got to an area of longer grass at the side of an athletics track, the youth, who was still holding the knife, forced her to undress and then raped her.

He pleaded guilty to the offence and was originally sentenced to six years in a detention centre last October at Woolwich Crown Court.

The court has increased the sentence to a 12 year extended sentence comprising of six years detention and a six year extended licence.

Speaking after the hearing, Attorney General Jeremy Wright QC said: “This attack left the victim fearing for her life. The original sentence failed to take proper account of the seriousness of the offence and the danger this young man poses to the public.

"I am pleased the court has now seen fit to increase his sentence, and I hope it can bring some comfort to the victim and her family.”

Speaking at the time of the sentencing, Detective Constable Robert Jamieson, of the Met's child abuse and sexual offences unit, said: "The suspect attacked a woman at knifepoint in broad daylight and subjected her to a horrific attack.

“He is clearly a very dangerous individual and I am pleased he is now behind bars and not able to cause further harm."
