Peter Tobin is one of Scotland's worst and most notorious serial killers. The cancer-stricken 75-year-old was jailed in 2008 after committing a string of killings between 1991 and 2006.
The Renfrewshire-born rapist and murderer, who has never shown remorse for his evil crimes, is currently serving three life sentences in HMP Edinburgh.
Tobin is also believed to be suffering from cancer, with several trips to hospital being reported in recent years. He was also rushed to hospital at the start of April after being floored with an unknown illness.
