An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and were later discharged.
Police detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of a number of people hurt by an irritating chemical thought 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 car park briefly.
