The prosecution at Preston Crown Court said Creegan then lay in wait and shot PCs Nicola Hughes and Fiona Bone repeatedly when they arrived before throwing a grenade towards the victims.
ITV News' North of England Correspondent Martin Geissler reports on the first day of the trial, which was attended by the families of both officers.
