A police officer accidentally fired a gun during a training exercise at Longannet Power Station.

The Police Investigations and Review Commissioner (PIRC) is making inquiries into the incident, which happened on December 14.

Police Scotland regularly uses the Fife power station for firearms training, it is understood.

In 2011, officers from Central Scotland Police used Longannet for a drill concerning the kidnapping of a government minister.

The PIRC said: "We are investigating the accidental discharge of a firearm in a training environment, located at the site of Longannet Power Station on December 14.

"The chief constable must refer certain serious incidents involving the police to the PIRC to allow for an independent investigation.

"A report on the findings will be submitted to the deputy chief constable in due course."
