A man stabbed to death at a London Underground station was an Arsenal fan on his way to a match.
Tashan Daniel, 20, was fatally wounded in an “unprovoked attack” on the platform at Hillingdon station on Tuesday shortly before 16:00 BST.
He had been heading to the Emirates Stadium to see the Gunners face Nottingham Forest in the third round of the Carabao Cup.
It is the third murder investigation on the Tube network this year.
Mr Daniel, who had recently celebrated his birthday, was on the platform waiting for a Piccadilly Line train into central London when he was attacked by two men, British Transport Police (BTP) have said.
Attempts were made to save Mr Daniel who was pronounced dead inside a Tube carriage.
Det Ch Insp Sam Blackburn said no arrests have been made, but both suspects left the station in the direction of Auriol Drive and a knife was recovered nearby.
“Tashan did not deserve to lose his life during this senseless attack,” he said.
“His family are completely broken by this news and we are doing everything we can to offer them support.”
Extra officers are going to be carrying out patrols in the Hillingdon area, Det Ch Insp Blackburn added.
Danielle Foster, who was driving past Hillingdon station at the time of the stabbing, said upon “hearing so many sirens, I knew something terrible had happened”.
“Lots of people were being turned away from the station as it had been closed,” she said, adding: “Then the police helicopter began circling the scene.”
Hillingdon station was closed by Transport for London (TfL) while police searched the area.
The station was closed for the rest of Tuesday evening and reopened at 05:45 this morning.
So far in 2019 more than 100 murder investigations have been launched across London by the Metropolitan Police and BTP.
