A prison officer has recalled the moment 30 years ago when inmates took over HMP Peterhead by taking him hostage.

On September 28, 1987, a riot within the jail resulted in prisoners taking over the building.

In images that shocked Scotland, prison officer Jackie Stuart was paraded on top of the roof of the jail's D-Hall that housed some of the country's most notorious criminals and was branded the 'hate-factory'.

The guard, who was 57 at the time, was held captive for five days during which he was routinely beaten by his captors and used a bargaining chip in ongoing negotiations.

The grandfather was stripped and dragged along the roof by a chain wrapped round his neck, like a dog on a leash.

His captors, made up of some the countries most violent prisoners, were protesting against jail conditions and the distance their families were forced to travel for visits.

The rioters were serving life in prison for violent crimes including rape and murder so it was believed that they would not hesitate to make good on their threats to kill the hostage as they had nothing to lose.

It was hoped the rioters would surrender after the initial spate of violence - and as many as 50 of them did so.

A hardcore group remained, however, and used burning barricades and booby traps to prevent guards getting to them.

They also still kept their chained-up hostage as a prized asset and main bargaining chip.

Jackie's ordeal only came to an end when then Prime Minister Margaret Thatcher decided it was time to take action to end the stand off after days of negotiations had broken down.

It was the eve of the Conservative Party conference and the party had been praising the success of their law and enforcement agenda so the Prime Minister was embarrassed some of the country's most dangerous convicts had managed to not only take over a prison but were holding an officer hostage.

It was in the early hours of October 3, 1987, when home secretary Douglas Hurd dispatched the SAS.

They stormed into D-Hall using stun grenades and gas as they rescued Jackie from his rooftop prison.

It was the first time the elite force had been deployed on mainland Britain and they ended the stand off in a six-minute raid of the notorious halls.

Rather than letting this experience put him off working as a prison guard, Jackie returned to work less than six weeks later and is in fact still working at Peterhead 30 years later.

Now 87, he is a tour guide at the prison after it was turned into a museum.

A new exhibition of Jackie's experience, with never before seen photographs, is now open at the museum.

Speaking of his experience in 1987, he said: "You never really knew what was going to happen. One of the guys who started it all was very erratic and you never really knew what he was going to do next.

"They put a chain around my neck and dragged me back and forward across the roof. It was continual beatings throughout the four days."

He was eventually rescued when the SAS were deployed in to the jail and the prisoner supposed to be keeping watch during the night had fallen asleep.

Mr Stuart said: "I just heard a slight scuffle on the roof then they threw in stun grenades and gas.

"The guy who was supposed to be keeping watch from the roof for anybody coming in but had possibly fallen asleep, landed on top me and that was them in."

When asked about his opinion on the men who captured him, beat him, chained him up, threatened his life and kept him hostage for days he simply says: "Well I am home to my family and they are not."
