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

It was late September 1987 when prisoners took over the prison building after a riot.

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.

The 57-year-old was held captive for five days where 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.

Jackie's ordeal came to an end when then Prime Minister Margaret Thatcher decided it was time to take action to end the stand-off by sending in the SAS.

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.

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

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."
