Two more people have been arrested in connection with a theft at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them 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 were taken to the hospital for treatment and were later discharged.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT following reports of several individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
