An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police arrested a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by a noxious substance thought to be an irritant spray.
The assault - which police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
