An additional two individuals have been arrested related to a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for medical care and were later released.
Officers arrested a 31-year-old man on suspicion of theft and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
