Two more people have been arrested related to a robbery at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for treatment and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
