An additional two individuals have been arrested related to a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
Police detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as 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.
