An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Officers arrested a 31-year-old man on suspicion of theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding several people injured by a noxious substance thought to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
