🔗 Share this article A Pair of Detentions in the Aftermath of London Heathrow Irritant Spray Attack This incident resulted in the temporary closure of the Central Terminal Area tunnel and the Terminal 3 car park. An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement. A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said. These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before 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 one of the those hurt during the incident. Five people were taken to the hospital for treatment and have since been discharged. Officers arrested a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue. Authorities were called 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 isolated and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
