An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the injured during the incident. Five people went to hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance believed to be an irritant spray.
The assault - an event that police said was a standalone incident 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 briefly.
