Mr Cathcart died on 7 December 2021 within HMP Barlinnie.

A preliminary hearing will be held on 28 August 2025 at Glasgow Sheriff Court.

Procurator fiscal Andy Shanks, who leads on deaths investigations for the Crown Office, said: “The lord advocate considers that the death of Brian Cathcart occurred whilst he was 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.”
