Detectives continue to appeal for anyone who attended a party where a teenager was fatally stabbed to come forward and speak with police.
Police were called at approximately 00:40hrs on Thursday, 27 October, to reports of a man stabbed inside the Basement Shisha Lounge in Goodmayes Road, Ilford.
Officers and London Ambulance Service attended and the injured man was taken to hospital where he died shortly after arrival. Next of kin have been informed and the deceased has been identified as Ziggy Worrell-Owusu, 19, (26.10.97) from Hackney.
A post-mortem examination took place on 28 October at East Ham Mortuary and gave cause of death as a stab wound.
Two 17-year-old males have been arrested in connection with the investigation, the first [A] on Friday 28 October, and the second [B] on Thursday 3 November. Both have been bailed to dates in mid-December.
It has been established that Ziggy had attended an 18th birthday party with a group of his friends at the venue and there were approximately 100 people in attendance. At some point during the evening an altercation occurred which led to Ziggy being stabbed.
Detective Inspector Euan McKeeve of the Homicide and Major Crime Command leads the investigation.
He said: "There were a large number of young people inside the Basement Shisha Lounge who would have witnessed this incident and the events that led up to it.
"Some of these people may be reluctant to tell police what happened, but I would urge them to come forward of their own accord and speak to us. We are working through the evidence in our possession to establish who was at the party and we will identify all those who were there.
"Ziggy was a popular young man and I would encourage anyone with information about this tragedy to come forward. One line of enquiry is that Ziggy stepped in to prevent a fight escalating between others.
"In addition to our earlier appeal for witnesses, I am also appealing to any partygoers who may, wholly innocently, be in possession of digital media or footage from the party to get in touch.
"I would also repeat my previous appeal to any parents whose teenagers attended the party: if you are concerned that your teenager may be a witness or unwittingly involved, please speak to them and contact us in confidence. We can discuss various ways you can support our investigation."
