An additional two individuals are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, 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 a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police arrested a 31-year-old man for suspected robbery and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals hurt by a noxious substance thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
