Protester admits damaging Stone of Destiny case

On the day of the incident, the court heard a tour guide had been taking a group of about 10 people through the crown jewels room when they heard someone shout: “This is a peaceful protest”.

At that point, the guide turned to see Madden standing in front of the cabinet with “various items” in his possession.

The guide pressed her panic button, which prevented further groups from entering the room.

She said she saw Madden holding a brick or stone, and attempting to smash the cabinet – which also contained the Scottish crown.

The guide told the court she then saw black spray paint being sprayed on to the cabinet.

Police were later called to the castle.

The court heard the cost of the damage was about £2,798.

Sheriff Kenneth Campbell adjourned the case until next month while he awaited background reports.

Madden will return to court for sentencing on 23 January.
