An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for medical care and were later released.
Officers detained a 31-year-old man for suspected robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by a noxious substance thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
