An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was detained 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-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers arrested a 31-year-old man for suspected robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
