A suspected burglar has been stabbed to death and the householder arrested on suspicion of murder after an attempted break-in at his house.
The balaclava-clad intruder and three others are believed to have tried to smash through the back door of the terrace house on Ethel Avenue, Salford.
The dead man, aged 26, is understood to have been carried away from the property by the gang as they fled.
Police were called and he was taken to hospital where he was pronounced dead.
Neighbours said the property was occupied by a man named locally as Peter Flanagan, who lives at the house with his son, Neil.
Police said two men, aged 59 and 27, and a woman, aged 21, were being held on suspicion of murder.
The incident comes after Prime Minister David Cameron promised stronger support for people protecting their property from burglars.
Next door neighbour, Sylvia Sharp-Cadigan, 67, said Peter Flanagan lived there with his son, Neil.
She described Mr Flanagan as a "worker" who left early in the mornings and his son as a "lad" who had a lot of visitors to the house. She added: "We are all upset because it is a quiet little street, we never have any bother. You don't like it on your own doorstep."
The house, part of a cul-de-sac, is next to an open area of scrubland close to a council recycling centre in the Pendlebury area of Salford.
