An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers arrested 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.
Police were alerted at approximately 08:10 GMT following reports of several people hurt by a noxious substance believed to be an irritant spray.
The attack - which authorities stated was isolated and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
