An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. Five people went to hospital for medical care and have since been discharged.
Police detained a man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The assault - which police said was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
