An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where 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 theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the those hurt in the event. Five people were taken to the hospital for medical care and were later released.
Police detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical thought to be an irritant 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 main airport tunnel and the Terminal 3 parking facility briefly.
