Two more people have been arrested related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the injured during the incident. A total of five individuals went to hospital for medical care and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
