Silvester

Ian Silvester, of Locks Hill in Portslade, East Sussex, had befriended his victims working as a babysitter, diving instructor, first aid trainer and St John Ambulance trainer.

Silvester, 60, was sentenced to 16 years in prison with an additional six years on licence at the same court on Friday.

Sentencing Silvester, Judge Christine Laing KC said: "You are the very definition of a paedophile hiding in plain sight."

An impact statement read out in court from one man who was abused by Silvester said: "You are a monster who picked the most vulnerable in society."

On devices seized from Silvester's home were images and videos of his victims being assaulted by him as well as indecent images of children, online chat logs and web searches of sexual interest in young boys.
