The mum of a Glasgow student who took her own life in prison has slammed the lack of an official investigation. 

Nearly three years after Katie Allan died at Polmont Young Offenders in 2018, a Fatal Accident Inquiry has still not been held. 

Solicitor to the family, Aamer Anwar has now written to the Justice Secretary Humza Yousaf, the Sunday Mail reports.

Katie Allan suffered from depression and it is believed she was enduring bullying in the cell.

She died at the age of 21 in June 2018, while serving a 16-month sentence for a drink-driving offence that led to a 15-year-old boy being knocked unconscious on Eastwoodmains Road in Giffnock. 

The solicitor's letter criticises a lack of progress in carrying out the FAI due to constant delays, made only worse by the Covid-19 outbreak. 

His letter adds: "Linda Allan has done more than any other to expose the deep-rooted ­problems at the heart of our Scottish prisons.

"The irony is that she is unlikely to be able to even be represented at her daughter’s FAI as she would not be ­eligible for Legal Aid.

“She certainly deserved ­punishment.

“But this is ­Scotland, this is the 21st ­century, what Katie did not deserve, was the ­horrific ­experiences she endured daily at the hands of the Scottish Prison Service.

“Her family had hoped that her legacy would be that no other young person in ­Scotland experienced such a catalogue of catastrophic events.”
