 "UK police arrest man after people at Heathrow airport allegedly attacked with ‘form of pepper spray’")
London Metropolitan Police arrested an armed man on Sunday following reports of an assault involving a “form of pepper spray” at a multi-storey car park at Heathrow Airport’s Terminal 3.
The incident, which occurred shortly after 8:00 am (0800 GMT), was reportedly triggered by an argument among “a group of people known to each other,” police confirmed. Crucially, authorities are not treating the episode as terrorism.
The Metropolitan Police dispatched armed response officers to the scene after receiving multiple reports of assaults. “A number of people were sprayed with what is believed to be a form of pepper spray by a group of men who then left the scene,” a police statement detailed. One man was subsequently arrested on suspicion of assault and remains in custody as enquiries continue to identify and trace other suspects involved.
