An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later released.
Police arrested a 31-year-old man on suspicion of theft and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT following reports of several individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
