London had quite the morning — and no, not because of the weather. A 31-year-old man was arrested Sunday after a robbery at Heathrow Airport turned into a pepper-spray fiasco, leaving 21 people needing medical treatment… including a 3-year-old child. Quite the accomplishment for a group of criminals who couldn’t even steal a suitcase without causing mass chaos.

According to the Metropolitan Police, four men robbed a woman inside an elevator at Heathrow’s parking garage. As if stealing her suitcase wasn’t enough, they decided to spray what’s believed to be pepper spray in her direction, hitting not only the victim but everyone nearby. Nothing says “modern urban safety” like getting ambushed in an airport elevator.

Witnesses told The Associated Press that the suspects appeared to be three young men dressed entirely in black with their heads covered — because of course they were. After the attack, they fled the scene, leaving behind a cloud of irritant and a whole lot of coughing travelers.

Video from the incident showed officers rushing in with large firearms as they navigated the multi-story parking garage. London authorities emphasized that the victim and suspects knew each other and, thankfully, this wasn't a terrorism-related incident — just your average “argument” that magically escalated into spraying 21 people, including a toddler. Truly reassuring.

Commander Peter Stevens explained, “At this stage, we believe the incident involved a group of people known to each other, with an argument escalating and resulting in a number of people being injured.” He also thanked the public for their cooperation — patience is a virtue, especially when travel plans are derailed by pepper spray in an elevator.

The arrested man is being held on suspicion of assault, and police are still searching for the remaining suspects who managed to escape. Ambulance crews treated victims on-site, sending five to the hospital, though authorities say none of the injuries are believed to be life-threatening.

The chaos caused hours of travel delays for both arriving and departing passengers, but Heathrow says operations have since returned to normal — a small victory after a morning that was anything but.

And hey, at least no one tried to blame this on “airport infrastructure” or “global instability.” Sometimes criminals are just criminals — and seeing authorities actually catch one is always a reminder that some things can go right.
