Two more people have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for medical care and were later released.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
