An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people went to hospital for treatment and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
