An additional two individuals have been arrested related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to 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. A total of five individuals were taken to the hospital for treatment 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 under investigation while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
