Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, as stated by 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 arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for medical care and have since been released.
Police arrested a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated 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 briefly.
