Eleven people are being held on suspicion of murder after a fatal stabbing in central London.
The Metropolitan Police said the male victim died at a hotel in Euston Street, Camden, on Monday night.
He had entered the building from the street before collapsing in the lobby.
One guest at four-star The Wesley, which brands itself as the first ethical hotel in the UK, said he heard things “kicking off” as he was trying to go to sleep.
Ayesha Begum, 38, who lives close to where the man was found, said she came out of her home after hearing a commotion.
“Police were following a trail of blood,” she said.
Laura Collings, 34, another hotel guest who is on a business trip from Manchester, said she returned to the hotel shortly after the man’s body had been taken away.
In the aftermath of the stabbing there were “quite a few people walking around looking upset” who seemed like “they might have been associated in some way” with the victim, she said.
Staff came to his aid and police were called to the scene at about 10.45pm.
The man was pronounced dead about 45 minutes later.
The suspects were taken into custody at separate London police stations, the force said.
Scotland Yard said inquiries were taking place to identify the victim and inform his next of kin.
A post-mortem examination will take place in due course.
Officers remain at the scene and cordons are in place.
