Heathrow Airport descended into chaos on 7 December 2025 when a group of four men robbed a woman of her suitcase in a Terminal 3 car park lift, unleashing what police believe was pepper spray and injuring 21 bystanders in the process.
The pepper spray attack, sparking fears of a larger threat amid rising airport security concerns, prompted an immediate lockdown with armed officers swarming the multi-storey facility, halting traffic and rail services for hours.
