Two more people are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Police detained a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical thought to be an irritant spray.
The assault - which police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
