Two more people are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers detained a man in his thirties on suspicion of theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several people hurt by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
