Two more people have been arrested related to a robbery at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them 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 treatment and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was isolated and not being treated as an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
