A BULLET was lodged in the wall of a city police station after a home-made gun went off as it was being inspected by forensic experts.
The makeshift weapon had been confiscated in a raid on a property in Leith on April 11.
The accident happened three days later as forensic specialists examined the gun at Gayfield Square police station.
Scottish Police Authority forensics chief Tom Nelson said: “Two forensic science staff were carrying out an examination of a home-made firearm.
“During this inspection the weapon was discharged and a projectile was lodged in the wall of the room, No-one was injured in this incident.”
Details of the incident only emerged in a report for a meeting of the SPA this week.
Investigations have been launched into the accident by both the Health and Safety Executive and the Police Investigations and Review Commission (PIRC), which is informed of every “unintentional firearms discharge”.
A PIRC spokesman said: “A report will be passed to the Deputy Chief Constable and the chief executive of the Scottish Police Authority.”
A man and a woman have appeared in court following the raid.
David Riddell and Ishbel Mackay, both 36, appeared at Edinburgh Sheriff Court on April 15, charged in connection with the seizure of the weapon. The case was continued.
