An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be pepper spray.
The attack - which police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
