Armed police were seen stalking through one of London’s busiest airports as they responded to a mock-up terror attack.
Stansted Airport staff joined police officers taking part in a simulation attack in the early hours of this morning.
The scenario was run by the Manchester Airports Group and involved a terrorist firearms attack during which police officers intercepted a number of subjects.
It was part of an ongoing training and exercising programme ensuring Essex Police officers and airport staff are ready for any challenge.
Deputy airport commander Chief Inspector Richard Phillibrown said: "This was a really positive exercise where we were able to test our response to a would-be terror attack.
"During the live play, we tested our tactical response to terrorists with firearms and how we would deal with the challenge in practice.
"Stansted is the UK's fourth busiest airport and more than 26 million passengers pass through there each year so it's essential we're prepared for any eventuality.
"There's no specific intelligence currently to suggest there may be an attack at Stansted but as the UK terror threat level is at 'severe' it's really important we carry out these exercises to make sure we're ready should the worst happen.
"I hope these kinds of exercises also give the public confidence that they are safe when using the airport.
"I'd also like to thank Manchester Airport Group and all the staff at Stansted for their support and co-operation."
