An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
