An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases 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.
Police detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT following reports of a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - which authorities stated was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
