Dale Cregan 'lured PCs to their deaths'
Two unarmed police officers were shot dead in Manchester last year after being lured to a house following a call about a burglary, a court has heard.
Dale Cregan, 29, is accused of killing Fiona Bone and Nicola Hughes last September. He is also charged with the murders of father and son David and Mark Short.
He denies the charges.
