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.
A spokesman for the Premier League club said: “Everyone at Arsenal Football Club is shocked and deeply saddened to learn of the tragic passing of Arsenal fan Tashan Daniel.
“Our thoughts are with Tashan’s family and friends at this sad time.”
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) said.
Attempts were made to save Mr Daniel who was pronounced dead inside a Tube carriage.
Det Ch Insp Sam Blackburn said no arrests had 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.”
The station was closed by Transport for London (TfL) while police searched the area.
It remained closed for the rest of Tuesday evening and reopened at 05:45 on Wednesday.
So far in 2019 more than 100 murder investigations have been launched across London by the Metropolitan Police and BTP.
They say every dog has its day, and some quick thinking from the Leyton Orient kit man ensured canine Pavo would live to fight another day.
The League Two side’s team coach was travelling to Mansfield for Tuesday’s game, on a slip road joining the A12, when Ada Martin spotted a dog racing across the busy road.
Pavo darted in front of a truck – which thankfully came to a halt – allowing the O’s kit man to run out, call to his furry friend and pick him up, with “tail wagging”.
A call to the number on Pavo’s collar found his family, with an Orient fan looking after it at a nearby hotel until dog could be reunited with owner.
Martin, a former club groundsman and mascot, will be hoping Pavo is Orient’s new lucky charm as Ross Embleton’s side look for a first away win of the season at Field Mill.
