Sadistic child killer Anwar Rosser has launched an appeal against his whole-life prison sentence.

Rosser’s legal team lodged the appeal with the Court of Appeal this week. A judge will decide in the next few weeks whether it goes to a full court hearing, or should be dismissed at the initial stage.

The 33-year-old psychopathic former soldier was sentenced to spend the rest of his life behind bars last month for the savage murder of four-year-old twin Riley Turner.

Riley was strangled and stabbed repeatedly while he slept in his bed at his family’s home in Harewood Road, Bracken Bank, Keighley, in January 2013.

Rosser pleaded guilty to the murder and was branded “an exceptionally dangerous man” who could kill another child, by the sentencing judge, Mr Justice Coulson.

The judge said the murder was a gross breach of trust of Riley’s family and he told Rosser he “must go to prison for life.

Rosser became only the 54th prisoner in the UK to be on a whole-life tariff, meaning they will remain in custody until they die.

Five of those – including Yorkshire Ripper Peter Sutcliffe and Crossbow Cannibal Stephen Griffiths – are from the Bradford district, which now has one-tenth of all whole-life prisoners.

Councillor Keith Dredge (Lab, Keighley West) said the news was “a blow” and could lead to Riley’s family and the wider community “reliving the trauma.”

Coun Dredge, who was proactive in supporting the community after the tragic death, said the appeal could also lead to more expense for taxpayers.

He said: “The guy is legally entitled to appeal, but I have faith in the British justice system.”

Rosser’s legal team had urged the judge to take into consideration recent judicial debate on the legality of whole-life tariffs, and asked him to step back from imposing one.

The European Court of Human Rights last year ruled the sentences must be reviewed, and the Court of Appeal will decide at a later date whether they should remain legal, though the Government insists whole-life tariffs are “wholly justified in the most heinous cases.”

Rosser is represented by Chambers Solicitors of Bradford. No-one was available for comment yesterday.

The Court Of Appeal confirmed Rosser had lodged an appeal against sentence.
