An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on 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. Five people were taken to the hospital for medical care and were later released.
Officers arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of individuals injured by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
