PCs Fiona Bone and Nicola Hughes didn't stand a chance as they responded to what they thought was a routine report of a burglary. The pair stepped out of their police van and walked up to the front door of a three-bed maisonette, into a slaughter that was so gratuitous the shock still reverberates today.Inside was one-eyed fugitive Dale Cregan - wanted for murdering two gangland rivals. Before the officers had even knocked, the merciless killer burst through the door, shouted 'police' and unleashed a hail of bullets on the two unarmed officers, probationers who had only just joined GMP. He tossed a hand grenade on their dying bodies and then calmly handed himself in at the nearest police station.
