An additional two individuals are now in custody related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery 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 come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage upon exiting 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 detained a man in his thirties for suspected robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
