§ Lord Aveburyasked Her Majesty's Government:
For each financial year from 1994–95 to the present, where and when riots have occurred in prisons; and what has been the cost of repairing damage caused and of relocating prisoners in each case. [HL3598]
§ Lord Williams of MostynThe Prison Service does not use the term "riot" as a definition of an incident. Under its incident reporting scheme, the only incident which could match this term would be that of active concerted indiscipline. Such an incident is defined as an incident in which two or more prisoners, acting together, use violence to disrupt the regime of an establishment. The associated costs of repairing damage and relocating prisoners are not available centrally and could be obtained only at disproportionate cost.
I am placing the available information in the Library.
