An additional two individuals have been arrested related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the injured during the incident. Five people 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 near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
