An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which 21 people 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 woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. Five people went to hospital for medical care and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance believed to be pepper spray.
The attack - which police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
