A man was stabbed multiple times after remonstrating with a gang who were throwing stones at a house in Bury.
At around 1.30am on Saturday 4 October 2014, a number of people were stood outside a house on Kingfisher Drive when they started to throw stones at the window.
A 22-year-old man walked outside and asked them to stop before he was hit with a stick. He returned to the house but stones were still being thrown.
The man walked back outside to remonstrate with them and gave chase.
When they reached a footpath at the back of Kingfisher Drive, the group turned on him and he was stabbed 15 times in the body and head. The offenders ran off before police were called.
The man is currently in a serious but stable condition in hospital.
Two 15-year-old boys, a 17-year-old boy and an 18-year-old man have been arrested on suspicion of attempted murder and remain in police custody for questioning.
Detective Sergeant Lawrence Dixon said: “When the man confronted the group and gave chase, he was set upon and stabbed numerous times. His injuries are serious and he is lucky to be alive.
“Due to the severity of this attack, we are treating it as attempted murder and I would appeal to anyone who may have witnessed the incident to contact us. Although we have made arrests, we are still investigating and asking for information.
“Obviously the local community will be deeply upset by what has happened but we have stepped up patrols in the area and are dedicated to finding out who is responsible.”
