A knife attacker who was living as a woman in a male prison has died behind bars, prison authorities have confirmed.
Sarah Riley, 29, died at HMP Perth earlier this month, the Scottish Prison Service said.
Riley – then known as Aiden – was given an order for lifelong restriction at the High Court in Edinburgh in December 2008.
She was 18 when she knifed a man in the back in Aberfeldy, Perthshire, while on probation for another assault.
Riley was handed a minimum two year eight month prison term – but warned she would be would be monitored for life.
It is understood she had been in Castle Huntly open prison as recently as 2017 – where it was claimed she had been involved involved in trysts with evil killer Henry Williamson.
However, she had later been transferred back to the maximum security Perth jail where she died earlier this month.
It is not known how she died and a fatal accident inquiry will be heard in due course.
A spokesman for the Scottish Prison Service said: “Sarah Riley, a prisoner at HMP Perth has died.
“She was convicted at Edinburgh High Court on 8 December 2008.
“Police Scotland have been advised and the matter reported to the Procurator Fiscal.
“A Fatal Accident Inquiry will be held in due course.”
