An additional two individuals are now in custody related to a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for treatment and were later discharged.
Police arrested a man in his thirties for suspected theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT following reports of several people hurt by a noxious substance believed to be pepper spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
