A teenager has been stabbed to death during a row believed to have spilled out from a pub.
A 25-year-old woman has been arrested on suspicion of murder after a the teenager, 18, suffered fatal injuries in Urmston, Greater Manchester, early today.
Police said they were alerted to a report of a group of men and women fighting on Flixton Road at 1.55am.
They found two men, both 18 and from Stretford, suffering from stab wounds. One was stabbed in the neck and leg and was taken to Manchester Royal Infirmary, where he is in a stable condition.
The other, who was stabbed in the chest, was taken to Hope Hospital, where he later died.
Detective superintendent Andy Peach, of the major incident team at Greater Manchester Police, said: "Clearly this is a shocking incident and a man has lost his life.
" From early accounts we believe there was an earlier verbal altercation outside the Ivory pub which escalated into violence and this tragic death.
"From what we can tell, the people involved in the disturbance knew each other.
"We have made an arrest but we believe there are outstanding offenders, which is why we are appealing for witnesses.
"This happened in Urmston town centre on a busy Friday night/Saturday morning and we know there were lots of people out at the time.
"If you saw this incident, or what happened in the lead-up, and we haven't yet spoken to you, then please get in touch.
"I would urge anyone who knows something to speak to officers from the major incident team and anyone else who has other concerns can speak to my officers, who will be providing an increased presence to provide the community with reassurance."
A post-mortem examination is due to be carried out later today.
Flixton Road near the scene, outside the Ivory pub, is expected to be closed for much of today.
