An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical thought to be pepper spray.
The assault - which police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
