Police investigating the fatal stabbing of a man who died in the lobby of a luxury central London hotel have released 11 people.
Four men and seven women, aged between 19 and 28, were arrested on Monday on suspicion of murder.
They have all been released on bail until mid-March in connection with the incident in Euston Street, Camden, the Metropolitan Police said on Wednesday.
Detectives are yet to establish the identity of the victim, who is believed to have been in his 20s.
Police were called to the hotel at 10.44pm on Monday night and the man, who was attacked in the street before he collapsed in The Wesley hotel, was pronounced dead at the scene about 45 minutes later.
Hotel staff were left in "complete shock" by the incident, according to The Wesley's chairman of directors, Reverend Stuart Burgess.
The "four or five" staff working near the lobby at the time are "trying to come to terms with it", he added.
Police inquiries are continuing and any witnesses or anyone with information concerning the stabbing is urged to call police on 101 quoting CAD 7945/18 Feb or Crimestoppers anonymously via 0800 555 111.
