A TIMBER firm worker has been warned he faces a "considerable prison sentence" after admitting to making indecent photos of children and possessing extreme images of animals.

Calvin Hardcastle, of Kingfisher Drive, Aiskew, near Bedale pleaded guilty at Northallerton Magistrates Court to having 13 images classed as the most obscene on June 28 last year.

The 30-year-old also admitted possessing 23 grossly offensive category B and 56 category C images or videos, some of which are understood to be cartoons.

Michael Hammond, prosecuting, said police had raided a property in Mowbray Road, Catterick Village and seized computer equipment after a tip-off.

When questioned by police over a Twitter user name, Hardcastle replied "no comment", said Mr Hammond.

Magistrates sent the case to Teesside Crown Court for sentencing.
