An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals 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 partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
