Heathrow lockdown: what do we know about Terminal 3?
Police received the call at about 8:11 a.m. and arrived to find that several individuals had been attacked in the Terminal 3 car park, according to an exhaustive statement from the Metropolitan Police. Armed officers stormed the building within minutes, arresting a 31-year-old man on suspicion of assault and carrying out a floor-by-floor search for at least three other suspects believed to have fled.
Crews from the London Ambulance Service triaged 21 people with coughs, sore throats and shortness of breath; five were taken to hospital, but none appeared to have injuries that were life-threatening or life-changing, according to broadcasters including Sky News. A three-year-old girl was among those treated at the scene. The car park is a detached building across the apron from Terminal 3, which was not closed, but the multi-storey complex itself was locked down while specialist officers and firefighters searched.
Police respondents reportedly suspected the confrontation started in a lift when a group of up to four men sprayed an irritant at a woman and took her suitcase, with the substance then rapidly affecting people in the lift lobby. Investigators say early reports indicate that the people directly involved knew each other and that it is being treated as a robbery targeted at individuals rather than terrorism, although a full motive has not been established.
As the airport closed stretches of its roads, forcing passengers to spend hours reaching terminals, other organisations were also fighting their battles against climate change. Some rail services — including Heathrow Express and Elizabeth Line links into central London — were believed to have been disrupted or stopped while emergency vehicles took precedence around the airport campus, according to various British media outlets.
What witnesses saw during the Heathrow lockdown
Passengers stranded during the Heathrow lockdown recounted panic suddenly engulfing the car park as people started coughing and covering their throats. One returning traveller told UK television he had seen several young men fleeing from the area around the elevator just as a sharp smell wafted through, followed by a “burning” feeling in his throat, after which pandemonium broke out as people stampeded for the exits.
Other witnesses claimed officers with guns and rifles stormed each level of the five-storey car park, telling motorists to remain in their cars as they hunted for suspects. Some motorists said they were detained for more than an hour until police slowly began releasing cars and letting traffic flow once again.
Police stressed that, despite the magnitude of the response and the dramatic scenes around Terminal 3, they had no reason to believe there was a broader threat to the airport. At least for now, detectives are examining CCTV footage, speaking with witnesses, and asking anyone who saw or filmed the robbery on a phone or dashcam to come forward.
Recent Heathrow lockdowns and scares prompt questions.
The Heathrow lockdown is the second such incident in recent months after Terminal 4 was evacuated for hours during an apparent hazardous material scenario, which sent some 20 people to treatment and one arrest in September, according to The Guardian’s account of the teargas scare. In that instance, a 57-year-old man was arrested on suspicion of having brought the spray into the terminal, and police emphasised it was not terror-related. Heathrow has suffered two other high-profile security breaches in the last few years that did not involve chemicals but still caused partial closures. In 2019, for instance, departures were briefly paused, and the military was deployed after a drone sighting over an airfield prompted flight suspensions, according to a report on the drone-sighting shutdown that year, which fueled broader discussion of airport perimeter security. at airports.
Those episodes and the latest pepper-spray heist have combined to cement passenger fears about how fast a seemingly localised incident can spiral into reports of a broader Heathrow lockdown — particularly in such enclosed environments as terminals or car parks. Airport officials say they keep reviewing their policies with police and emergency services, trying to strike a balance between an immediate, high-profile response and ensuring crucial air and rail links keep moving.
For now, officials say the lockdown at Heathrow on Sunday was an isolated criminal incident rather than part of a larger pattern of coordinated attacks. But with footage of tactical officers running through one of the busiest airports in the world being shared again by passengers after the episode, questions about security, crowd management, and communication during fast-moving scares are likely to remain for a while.
