An additional two individuals are now in custody related to a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people went to hospital for treatment and were later released.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance believed to be an irritant spray.
The assault - which 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 Central Terminal Area tunnel and the Terminal 3 car park briefly.
