An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at 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 those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several individuals injured by a noxious substance believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
