Eleven people arrested on suspicion of murder after a man was stabbed in the street and collapsed and died in a hotel reception have been released.
The victim, aged in his 20s, who has yet to be identified, entered the Wesley Hotel, near London’s Euston Station, at about 22:45 GMT on Monday.
He was helped by hotel staff but died shortly after 23:30.
Seven women and four men, aged between 19 and 28, have been released on bail until mid-March, the Met said.
The force added it was making urgent inquiries to identify the man and contact his family.
