An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, was arrested 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. They both remain in custody, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people went to hospital for treatment and have since been released.
Police detained a 31-year-old man on suspicion of theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
