On 18 September 2012, two Greater Manchester Police officers, Nicola Hughes and Fiona Bone, were killed by Dale Cregan in a gun and grenade ambush while responding to a report of a burglary in Tameside, Greater Manchester, England. The incident was the first in the United Kingdom in which two female police officers were killed on duty. Greater Manchester's chief constable Peter Fahy called the attack "cold-blooded murder" and then British prime minister David Cameron described it as a "despicable act...of pure evil".
