Two more people are now in custody in connection with a theft at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police detained a 31-year-old man on suspicion of theft and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at about 08:10 GMT following reports of a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
