An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be pepper spray.
The assault - an event that police said 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.
