Mr Anderson died on 26 December 2021 at the Queen Elizabeth University Hospital in Glasgow. He had been an inmate within HMP Glenochil when he was admitted to the hospital on 29 September 2021 for a bone marrow transplant.

The inquiry is a mandatory inquiry under section 2(4)(a) of the Inquiries into Fatal Accidents and Sudden Deaths etc. (Scotland) Act 2016.

A preliminary hearing will be held on 5 January 2024 at Glasgow Sheriff Court.

Procurator Fiscal Andy Shanks, who leads on fatalities investigations for COPFS, said: “The lord advocate considers that the death of Gregg Anderson occurred while in legal custody and as such a Fatal Accident Inquiry is mandatory.

“The lodging of the first notice enables FAI proceedings to commence under the direction of the sheriff.”
