An additional two individuals are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both are still being held, the force said.
These detentions come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by a noxious substance thought to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
