An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a man in his thirties on suspicion of robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
