A PAEDOPHILE who had nearly 13,000 child porn images and who sexually abused a teenage boy for five years has been told to expect a “heavy punishment”.

During a hearing at York Crown Court, John Alexander Stuart Black, 48, admitted 39 offences, including six charges of sexual activity with a child and one of causing a child to watch a sexual act.

Black, of Leeds Road, Tadcaster, also pleaded guilty to possessing 12,793 indecent photographs of children, 11 charges of making indecent photographs of a child, 15 of distributing indecent photographs of a child and five of possessing indecent photographs of a child with a view to them being distributed.

All 39 offences were committed between May 2004 and February 2010.

Black, who showed no emotion during the short hearing, was remanded in custody to await sentencing next month.

Before leaving the dock, the Recorder of York, Judge Stephen Ashurst, told him: “You have pleaded guilty to a large number of exceptionally serious sexual offences.

“Before sentence can be passed upon you, the court will need to consider reports that assess the risks you may pose in the future.

“All that material will help the court in deciding what is the right sentence for your particular offences.

“The fact you have entered your guilty plea is something that will count in your favour.

“No doubt you will have been advised by your solicitor and barrister that these are extremely grave offences for which you are likely to be heavily punished.”

The court heard Black had no relevant previous convictions.
