Detectives have named the 18-year-old boy who died after being stabbed at a warehouse party in East Acton .
Mahad Hussein Ali, from Crouch End, died at a central London hospital in the early hours of Thursday morning (June 29).
Police found him suffering stab wounds after being called to a warehouse party in Coronation Road to reports of a fight at around 2.35am.
Another man was treated at the scene for head injuries, and detectives are trying to establish if there were any other injuries at the party, which they believe was attended by around 40 to 50 poeple.
While formal identification has not yet taken place, Mahad's next of kin have been informed and detectives are 'satisfied' he is the victim.
Police believe the fight may have begun as an altercation inside the party which then spilled outside, resulting in Mahad's fatal stabbing.
A day on from Mahad's murder, no arrests have been made and police are appealing for information.
DCI Luke Marks said: "It is of paramount importance that those that were at the party and saw the events leading up to the stabbing or the incident itself come forward and speak to us.
"I appreciate that there maybe some apprehension about coming forward but I would ask that they do not delay in talking to us.
"Mahad's family have been left completely devastated and are desperately seeking answers as to why he was set upon and what sparked the altercation.
"Mahad suffered significant injuries and there is a strong possibility that person or people involved in the attack would have got blood stains on their clothing.
"I would appeal to anyone who knows that a loved one attended the party who either washed or threw away items of clothing when they returned home to approach us.
"Please do not remain silent. If you have the slightest indication that your loved one may have been involved now is the time to say something.
"To those mothers, sisters and girlfriends shielding the person or people responsible, please do the right thing."
