An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and have since been released.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding several people hurt by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
