Two more people have been arrested related to a robbery at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after a probe into an attack 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 during the incident. A total of five individuals went to hospital for treatment and were later discharged.
Officers arrested a 31-year-old man on suspicion of theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
