A murder investigation has been launched after a man was stabbed to death at a London Underground station.
Officers from the British Transport Police were called to Hillingdon Station shortly before 4pm on Tuesday following a report of a serious assault on the platform.
Members of the London Ambulance Service and air ambulance attended the scene and found the man with a serious injury consistent with being stabbed.
He was declared dead at the scene and his family have been informed.
Detective Superintendent Gary Richardson, from British Transport Police, said: “This was a shocking act of violence which has seen a man tragically lose his life this afternoon.
“While we are at the early stages of our investigation, we believe a group of young men were involved in an altercation on the platform before one of the men received a fatal stab wound.
“We are doing all we can to find those responsible, and I would urge any witnesses or anyone who was in the area at the time and saw anything suspicious to contact us as soon as possible.
“Please text BTP by texting 61016 or calling 0800 40 50 40 quoting reference 382 of 24/09/19. Alternatively, you can call Crimestoppers anonymously on 0800 555 111.
“This level of violence is not usual on the rail network, and we will be increasing our uniformed patrols in the Hillingdon area in the coming days to help reassure the travelling public.”
Hillingdon Station remains closed as inquiries are conducted by specialist officers and a cordon remains in place.
Transport for London confirmed there is disruption on both Underground lines at Hillingdon Station, as well as disruption to buses in the area.
The Metropolitan Line will now terminate at Ruislip station and the Piccadilly Line will stop at Rayners Lane station.
