An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft 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.
The arrests come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for treatment and were later discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance thought to be an irritant spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
