The family of a police officer who was killed in a gun and grenade attack in Greater Manchester yesterday have paid tribute to their "very caring and loving girl".
The family of Nicola Hughes, 23, said they were "exceedingly proud" of her, in a statement released today.
The father of the other police officer killed, Fiona Bone, 32, called for her killer to face the death penalty.
Paul Bone told the Daily Mail: "Anyone who kills an officer should be hanged".
Miss Bone and Miss Hughes were sent to investigate a "routine" burglary report when they were attacked.
According to a witness, Miss Bone was armed with a taser gun. The witness said: "She had a taser in her hand and she was laying by the window of the house".
Fugitive Dale Cregan, 29, who was wanted in connection with a separate gun and grenade attack that killed father and son David and Mark Short, gave himself up at nearby Hyde police station in Greater Manchester shortly after the two officers were killed.
It emerged last night that Cregan, who is being questioned in connection with killing Miss Bone and Miss Hughes, had previously been released on bail in June.
He was held at Manchester Airport, after returning on a flight from Thailand, in connection with the murder of Mark Short but was released on bail pending further inquiries.
Greater Manchester Police Chief Constable Sir Peter Fahy defended the bail decision in a statement today:
Cregan is thought to have made a fake burglary report before attacking officers Fiona Bone, 32, and Nicola Hughes, 23, Sir Peter said.
Sir Peter Fahy added that "it would appear Cregan has deliberately done this in an act of cold-blooded murder" and his motive for the attack was "impossible to fathom".
He added there was nothing to suggest that armed officers were needed to attend the burglary.
Sir Peter said he believed Cregan had been "protected by a criminal conspiracy to harbour him". He said the force was "fully determined" to investigate that idea and bring those involved "to book".
The Chief Constable paid tribute to Miss Bone, calling her an "excellent bobby" who had been in the middle of planning her civil ceremony.
He said Miss Hughes was a "chatterbox" and "great bobby" who was "always smiling".
Sir Peter said the force was "absolutely devastated" and "shattered" by the shootings, which amounted to "one of the darkest days" for Greater Manchester Police.
Eyewitnesses said a hail of bullets were fired and a grenade was used during the attack shortly before 11am.
Sir Peter said Cregan had not contacted police at any time during the manhunt or made any threats to police officers.
But he added that police had been looking at a range of scenarios including Cregan trying to kill other people as a result of the gangland feud he was involved in.
And he said there was "concern" that he might target police officers.
