An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
