An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
