Two more people are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of a number of people injured by a noxious substance believed to be pepper spray.
The assault - an event that police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
