An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers 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. Five people went to hospital for medical care and were later released.
Officers detained a 31-year-old man on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be pepper spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
