SIR David Murray’s dad was banged up in Glasgow’s tough Barlinnie Prison after being convicted of fraud.
Ian was locked up for 12 months after he ‘took the fall’ for a disastrous business deal.
Recalling the trauma of the jail term, Sir David said: “He was initially sent to Glasgow’s Barlinnie jail and it was a daunting experience going there to visit him.
“But within weeks, he had been transferred to Penninghame Open Prison near Newton Stewart in south-west Scotland.
“My father struggled to recover from his experience there.
“He died in Ballochmyle Hospital on September 20, 1975 at the age of just 50.”
Elsewhere in his new book, Sir David told how he still has shards in his leg from the wreckage of the sports car that nearly killed him in a horror crash almost half a century ago.
The ex-Rangers owner was just 24 when he had both legs amputated after the flash motor careered into a tree following a tyre blow-out in 1976.
Despite the horrific accident, he refused to let the ordeal define him and went on to become a towering figure in Scottish society through his metals business and Ibrox tenure.
Sir David, 73, became a millionaire with company Murray International Metals and purchased Rangers for £6million in 1988.
