🔗 Share this article Two Detentions Following London Heathrow Irritant Spray Attack This incident caused the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park. An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, according to police. A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed. These detentions follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift. A toddler aged three was one of the injured in the event. Five people were taken to the hospital for medical care and were later released. Police detained a 31-year-old man for suspected robbery and assault close to the scene. He was subsequently released under investigation while inquiries continue. Police were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray. The assault - an event that authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
