A search has been launched for a child rapist who escaped while on 'escorted community leave' in Perth city centre.

Cliff Lyons Dobbie, who is a restricted patient, is described as a white male, about 5ft 3in (1.6m) tall and of stocky, muscular build.

He has been detained in secure units since 1990 after he raped a 10-year-old girl in Glasgow.
