An additional two individuals have been arrested related to a theft at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, 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. Five people went to hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical thought to be an irritant spray.
The assault - an event that police said was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
