A Scottish prison officer has walked free from court despite being caught possessing extreme donkey porn and child abuse images.

Peter Sugden, 46, from Falkirk, delivered 'intensive' rehab courses to sex offenders but has now been placed on the register himself following the grim discovery.

Sugden's home was raided by police in June last year after he was caught in a 'sting' set up by a London-based group of paedophile hunters.

The former HMP Edinburgh officer appeared for sentence at Falkirk Sheriff on Tuesday after pleading guilty at an earlier hearing to communicating indecently with someone he was under the impression was a child named Abbie.

But this was actually an adult female decoy named Sonia.
