Calum Inglis, 34, died in his prison cell at HMP Addiewell in West Lothain after he tested positive for Covid-19 in October 2021.

He was serving a three-year sentence for assault when he tested positive. Asthmatic and unvaccinated, he died on October 24 after his health declined rapidly.

His family say that in the 12 days after he tested positive he was not seen by a nurse despite being breathless, coughing up blood and repeatedly requesting medical attention via his intercom.

Lord Advocate Dorothy Bain KC met with his family yesterday and has instructed the prosecution of Addiewell Prison, which is run by Sodexo Ltd, and NHS Lothian over their alleged failures.

Ms Bain said: “I understand the tragic loss felt by Calum’s family and their wish to know what happened to him and would like to thank them for meeting with me today to talk about the progress of the investigation.

“I am committed to ensuring that the facts and circumstances surrounding Calum’s death are thoroughly investigated by the relevant agencies, fully considered by COPFS and aired in the appropriate legal forum.

“The family and their legal representative will continue to be kept updated in accordance with their wishes.”

A spokesperson at HMP Addiewell said: “We understand that this continues to be a very difficult time for Mr Inglis’s family and our thoughts and condolences remain with them.

“It would be inappropriate to comment further at this stage, but I can confirm that we are continuing to work with all relevant authorities in advance of any future fatal accident inquiry.”
