Emergency services are dealing with an incident at Heathrow Airport.
Trains and buses to the transport hub were halted on Sunday morning as police rushed to reports of a “serious incident” in the Terminal 3 car park.
A spokesperson for Heathrow Airport said: “Our teams are responding to an incident with the emergency services in the multi storey car park in Terminal 3. We will provide updates shortly.”
The M4 Spur Road to and from Heathrow Terminals 2 and 3 was temporarily blocked, but has now reopened, according to National Highways.
Train lines are also experiencing disruption, with the Elizabeth Line also briefly closed So far at least 17 trains serving Heathrow Terminals 2 and 3 have been cancelled – or have run through without stopping.
Terminal 3 is used by Virgin Atlantic, Delta, Emirates, Cathay Pacific, Qantas and many other major airlines. The multi-storey car park where the incident unfolded is directly opposite the check-in area.
The Independent understands that the incident is not thought to involve either terrorism or protest.
National Highways previously said the M4 Spur Road had been closed as teams responded to a “serious incident”. In a post on X it confirmed the road had reopened and said the incident had been “resolved”.
Eyewitnesses reported seeing “armed police” on the scene with bus drivers reportedly instructed not to leave their vehicles. The exact nature of the incident is not yet clear.
The Metropolitan Police has been contacted for more information.
