An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for treatment and were later discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT following reports of a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
