THREE people remain in police custody today after a man was stabbed to death during a party.
Police launched a murder investigation after the victim, identified as Cole Wilson, was found with multiple stab wounds.
Emergency services were called to a house in Sledmere Close, Peterlee, shortly before 3am yesterday where they discovered the 20-year-old from Walker, Newcastle, in the living room covered in blood.
Paramedics tried to revive Mr Wilson, but he was pronounced dead at the scene.
Two women, aged 24 and 20, were arrested at the semi-detached house and later in the morning officers from Northumbria Police, acting on behalf of their colleagues in Durham, arrested a 19-year-old man at an address in Holywell Avenue, Walker.
He and the two women were being held on suspicion of murder.
A man and a woman were also arrested by Northumbria Police at the house in Walker on suspicion of assisting an offender and were later released on police bail.
Much of Sledmere Close in Peterlee was cordoned off yesterday to allow forensic examination of the scene and officers carried out house-to-house inquiries.
The murder weapon, thought to have been a knife, has not been traced.
About 30 detectives and other specialist staff are working on the case and an incident room has been set up at Peterlee police station, under the supervision of the senior investigating officer, Det Supt Ken Donnelly.
The victim, who has not yet been identified, is thought to be from the Walker area, but it is believed those involved knew each other.
A post mortem was due to be carried out last night to determine a formal cause of death.
Det Chief Insp Steve Chapman said: “We would be keen to hear from anyone who heard a disturbance or noticed anything unusual in the Sledmere Close area of Peterlee in the early hours of Sunday.
“Crimes involving bladed weapons are relatively rare in our force area, but sadly on this occasion it would appear a young man has lost his life in such a way.”
Residents living in Sledmere Close said they were shocked this had happened in their street, but said the people in the house where the incident took place only moved in from the Newcastle area a few months ago.
Alison O’Hara, 44, who lives in the street with her three children, said: “I was just settling down for the night when I heard a scream. I didn’t think anything of it, I just thought it was people carrying on coming from the nightclub. Then about 10 minutes later the whole place was swarming with police.
“It’s a big shock, you expect things like this to happen somewhere else, not in your own street.”
Katie Craggs, 21, who lives just a few doors from where the incident happened, said: “I didn’t know a thing about it until I got up this morning and saw all the police tape. It is a shock for something like this to happen.”
