Serial killer Peter Tobin has been taken to hospital from the prison where he is serving three life sentences.
Tobin was taken to the Royal Infirmary of Edinburgh from HMP Edinburgh on Thursday after becoming unwell.
He is serving a life sentence for raping and murdering Polish student Angelika Kluk, 23, and hiding her body under the floor of a Glasgow church in 2006.
Tobin, who is aged in his mid-70s, is also serving life terms for the murders of 15-year-old schoolgirl Vicky Hamilton, of Redding, near Falkirk, in 1991, and 18-year-old Dinah McNicol the same year.
Their bodies were found 17 years later, buried in the garden of his former home in Margate, Kent.
A spokesman for the Scottish Prison Service said: “We cannot comment on individual prisoners.”
It is not the first time Tobin has been taken to hospital from prison in recent years.
In February 2016 he was taken to the Royal Infirmary by ambulance after he reportedly collapsed in his cell.
