An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and have since been released.
Police detained a 31-year-old man for suspected robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance believed to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
