An additional two individuals have been arrested in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of a number of people injured by an irritating chemical believed to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
