Manchester police call for end to crime family feud that led to officers' deaths Police have called on two feuding crime families in east Manchester to end the dispute that led to two police officers being shot dead in Tameside earlier this week. PC Nicola Hughes, 23, and Fiona Bone, 32, died while responding to a report of a burglary at Abbey Gardens, on the Hattersley estate in Mottram, on Tuesday morning. A post-mortem examination revealed both officers died of gunshot wounds. On Thursday, assistant chief constable Garry Shewan said it would be wrong to portray Manchester as being in the middle of a gang war. "This would overestimate what we have got here: clearly two feuding criminal families," he said. He went on to declare that "enough is enough," and that Tuesday was a watershed moment that had to be the end. The ACC said a 22-year-old man in Netherley, Merseyside, has been arrested under the Communications Act 2003 after an offensive Facebook page was set up following the officers' deaths. The arrest is thought to be linked to a Facebook page that appeared to praise 29-year-old Dale Cregan, the man police arrested on suspicion of four murders, for his alleged involvement in the killings. The 22-year-old is in police custody for questioning. Meanwhile, Greater Manchester chief constable Sir Peter Fahy visited the scene where the officers were killed. He stood in silence alongside colleagues, heads bowed, among the bouquets left in tribute. He described them as "two wonderful human beings, two very dedicated officers." He said earlier in the day he had spoken to both their families and recounted some of the kindness they had shown to victims of crime. And he said the families were grateful for the "massive show of public support." Fahy said: "The two families are just overwhelmed by the huge support they are getting right across the country." Officers are in discussion with the Crown Prosecution Service about charges, he added, and he expected that there would be developments in the next 24 hours. Speaking earlier, his colleague Shewan said: "In the last 48 hours, since the tragic death of our two officers, there has been a huge amount of support from the public through our website and on social media. Shewan said they had become "very aware of the derogatory and offensive comments," but the overwhelming public reaction on social media remained one of support. An online book of condolence has attracted many thousands of messages from wellwishers and a Facebook page set up by the force has been viewed by more than a million people. It was, he added, the worst day in his policing career, and the force was still coming to terms with "the loss of two wonderful, first-class young officers." He said it would do everything it could to rid Greater Manchester of organised crime . An unnamed source claimed in the Manchester Evening News that if you know the right people, you can pick up grenades for as little as £50. But the force dismissed claims that the gun used in the shootings had been supplied by Steven Greenoe, an American who was jailed in the US for importing gun components to the UK. Greenoe, of Raleigh, North Carolina, bought the guns in the US, broke them up and hid them in his luggage before travelling to the north-west of England on commercial flights. Police were granted more time to question Cregan, giving them until 8am this morning before he must be charged or released. On Wednesday, a 28-year-old man, Stephen Garvey, who lives on the estate was arrested on suspicion of conspiracy to commit murder. He is being questioned by police. Shadow home secretary, Yvette Cooper, who visited the estate, said: "I think obviously they have been very shocked and frightened by what has happened, but I think the strong feeling everyone has now is that they want justice to be done for the officers who have been killed." The BBC shelved the final episode of its programme, Good Cop, scheduled to be shown at 9pm on Thursday on BBC1, in the light of the deaths.
