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 an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people went to hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
