Police Scotland were called to Holyrood on 21 occasions following reports of thefts, threatening behaviour and vandalism in the 12 months to April of this year.
The number of parliamentary crimes has almost doubled on the previous year’s figures, when 11 complaints – including reports of breach of the peace – were filed.
A Freedom of Information response from Police Scotland shows that, in the past year, there were four reports of threatening or abusive behaviour and two of vandalism.
