An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
