An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. Five people were taken to the hospital for medical care and were later discharged.
Officers arrested a man in his thirties for suspected theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
