An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on 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 medical care and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of several people hurt by a noxious substance thought to be an irritant spray.
The attack - which police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
