Pair arrested over Luton New Year's Eve party death
Two teenagers have been arrested after a man died in a suspected stabbing at a New Year's Eve party in Bedfordshire.
Police and ambulance crews were called to an address in Helmsley Close, Luton, at about 03:00 GMT.
The man, 42, from Luton, died a short time after being assaulted at the house party, police said. He had suffered a "chest wound".
A teenage boy and girl, whose exact ages have not been released, are being questioned.
They are being held at Luton Police Station as part of the murder inquiry.
A police spokeswoman said: "The victim was at the party at his partner's house, which was also attended by a number of youngsters when the incident occurred.
"Inquiries continue to establish what the altercation was about and what led to the victim receiving fatal injuries."
Officers are appealing for people who were at the event to come forward. The area is cordoned off as detectives investigate the death.
Neighbours said "loud music" had been played at the house.
One resident, who declined to be named, said: "I had gone to bed early and heard music from up the road.
"There were young girls running up and down the road screaming. There must have been quite a few people at the party."
The man was found outside the property, in the town's Hockwell Ring area, and was pronounced dead within an hour of emergency services arriving at the scene, the spokeswoman said.
An ambulance service spokeswoman said the man had suffered a "chest wound".
"We were called to the scene at 03:06 GMT and the patient was in cardiac arrest," she said.
"He had suffered a chest wound and cardiopulmonary resuscitation was being carried out on the patient on our arrival. By 03:30 GMT, we had left the scene with the patient and he was taken to Luton and Dunstable Hospital."
Post-mortem tests are due to take place later.
