An additional two individuals are now in custody related to a theft at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for medical care and have since been released.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
