🔗 Share this article A Pair of Detentions in the Aftermath of Heathrow Irritant Spray Attack This incident resulted in the temporary closure of the CTA tunnel and the T3 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 law enforcement. A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said. These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their suitcases after getting out of a parking garage elevator. A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later discharged. Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds. Police were alerted at about 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be an irritant spray. The attack - which police said was isolated and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
