An additional two individuals have been arrested related to a theft at Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of a number of individuals injured by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
