A probe has been launched after a consultant was found dead in an operating theatre at Aberdeen Royal Infirmary.
Police and medical staff are investigating the sudden death of Dr Paul Holder, a consultant anaesthetist.
It is understood medical equipment was involved in the death.
Police were called to the Foresterhill site at around 5.20pm on Sunday after a member of staff discovered the body. There do not appear to be suspicious circumstances, Police Scotland said.
Part of 44-year-old Mr Holder’s role at the hospital involved assisting and teaching students at the medical school.
Professor Alan Denison, medical school programme lead, broke the sad news to staff and students in an email.
He wrote: “Whether you were taught or supported by Paul, his death has come as a great shock to those who worked closely with him.
“We are working closely with the anaesthetics department in Aberdeen to support them and students who are attached there.”
