An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an attack 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 upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people went to hospital for treatment and were later released.
Police arrested a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of a number of individuals hurt by an irritating chemical believed to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
