An additional two individuals have been arrested related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties for suspected robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT following reports of a number of people injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
