A murderer who killed a Keighley child is appealing against an order that he must spend the rest of his life behind bars.

Anwar Rosser will have his whole-life sentence challenge heard today by the Lord Chief Justice Lord Thomas, Mr Justice Wyn Williams and Mr Justice Sweeney at the Court of Appeal in London.

Former soldier Rosser, 33, who admitted murdering four-year-old Riley Turner in a "savage and gratuitous" attack, was handed a whole-life tariff by a judge at Bradford Crown Court in February.

Rosser, of Harewood Road, Bracken Bank, was staying at the boy's home in Keighley, in January last year, when he stabbed and strangled the "happy and bubbly" child as he lay in his bed.
