In the year 9 May 1990 to 8 May 1991 there were 30 security alerts in closed prisons requiring a full search of the prison and 19 alerts which "presented a significant threat to control." There were an additional four full searches of open prisons.
The full search alerts at closed prisons included 11 bomb threats, 7 firearms alerts, and two losses of security keys. The alerts involving "threat to control" largely concerned refusal by prisoners to return to cells or to leave the exercise yard, and five rooftop demonstrations. Control and restraint teams were used in three incidents.
