🔗 Share this article Two Arrests Following London Heathrow ‘Pepper Spray’ Incident The assault caused the temporary closure of the Central Terminal Area tunnel and the Terminal 3 car park. Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to police. A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said. These detentions follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator. A toddler aged three was one of the those hurt in the event. Five people were taken to the hospital for medical care and were later discharged. Police detained a man in his thirties on suspicion of robbery and assault near the scene. He has since been released under investigation while inquiries continue. Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be pepper spray. The attack - which police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
