An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
