Two more people are now in custody related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Police arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT following reports of several individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
