Two more people have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by 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 conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for medical care and were later discharged.
Police arrested a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT after reports came in regarding several people injured by a noxious substance believed to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
