Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the those hurt during the incident. Five people were taken to the hospital for treatment and were later released.
Police detained a man in his thirties for suspected theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of several people hurt by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
