A teenage girl is thought to have been mauled to death by "aggressive and out of control" dogs at a house.
The 14-year-old, believed to be Jade Anderson, was found dead at a property in Chaucer Grove, Atherton, Wigan, shortly after 2pm on Tuesday following reports that she was unconscious and a number of dogs were out of control.
Armed police officers destroyed four of the animals, thought to be two bull mastiffs and two Staffordshire bull terriers, while a fifth was contained, Greater Manchester Police (GMP) said.
Superintendent Mark Kenny said the teenager's injuries were "consistent with her having been attacked by dogs".
Locals said Jade was visiting the property to see a friend, Kimberley Concannon, 16, who lives there with her twin Catrina and mother Beverley Concannon.
Signs at the front and back of the two-storey red brick house warn: "Beware of the Dog."
Youngsters who knew Jade said they had spoken to Catrina, who was not at the property when the dog attack happened but apparently said Jade "had a pie in her hand" at the time of the incident.
One 15-year-old said Carina had told her: "She moved the pie and the dog's gone for her throat and then they have all gone for her."
A post-mortem examination to establish how Jade died is expected to take place later on Tuesday evening. The dogs' remains will also be examined as part of the investigation, police said.
Neighbour Kenneth Lindsay said he heard gun shots being fired. "I just heard gun shots. It was going on without me realising it," he told ITV News. "When I heard the gun shots I came out of the door. There was a policeman talking to people. I went down... to see what it was all about and the policeman shouted at me to get back inside and stay inside."
