A notorious sex beast who tortured a woman with learning difficulties 20 years ago is back behind bars after falling for a suspected online sting.
James Mercer subjected the helpless victim to a depraved catalogue of rape and humiliation and was sentenced to ten years in 2002.
Mercer, 55, was jailed for 18 months at Edinburgh Sheriff Court on Thursday for violating the terms of an order designed to protect the public from him.
