An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in Lambeth on suspicion of 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.
These detentions follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt in the event. Five people were taken to the hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 8:10 in the morning GMT following reports of several people injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
