An additional two individuals have been arrested related to a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on 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 those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The attack - which police said 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.
