An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at about 8:10 in the morning GMT following reports of several people hurt by a noxious substance believed 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 main airport tunnel and the T3 car park for a short time.
