Authorities have foiled two attempts in a week to breach security at Perth Prison by drone-flying criminals trying to smuggle in illicit items.
Officers thwarted attempts on September 22 and 25 when prison staff alerted Police Scotland after spotting the drones being flown into prison grounds.
Officers are still investigating their contents and it is understood they contained prohibited items.
A spokesman for the Scottish Prison Service confirmed they were aware of the latest drone incidents.
“The police took away both drones and they are now investigating what is in them,” he said.
“However, we have had issues with drones at Perth Prison before on a number of occasions. These haven’t taken place frequently but they have consisted of attempts to introduce contraband into the prison.
“We work with our partners to detect the introduction of such contraband and this includes the support of the neighbouring community using schemes like Prison Watch, where residents notify the prison authorities if they see any suspicious activity in the area.
“This has already led to a number of convictions for people trying to introduce contraband into prisons.”
Chief Inspector Ian Scott, area commander for Perth and Kinross, said police couldn’t reveal what was contained in the drones but said officers were aware of attempts to introduce controlled drugs and phones into the prison.
These recent incidents follow an attempt last year in which a drone destined for the prison was recovered in a nearby garden. It contained items including diamorphine, cannabis, mobile phones and superglue.
