Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for treatment and were later released.
Police arrested a 31-year-old man 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 injured by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
