Two more people have been arrested in connection with a theft at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the those hurt during the incident. Five people were taken to the hospital for treatment and were later released.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of several people hurt by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
