🔗 Share this article Two Arrests Following Heathrow Irritant Spray Attack This incident resulted in the temporary closure of the CTA tunnel and the Terminal 3 car park. Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police. A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, the force said. These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator. A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for medical care and have since been released. Police arrested a 31-year-old man for suspected theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds. Police were alerted at about 08:10 GMT after reports came in regarding a number of people injured by a noxious substance thought to be an irritant spray. The assault - which police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
