Two more people are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people were taken to the hospital for treatment and were later released.
Officers detained a man in his thirties for suspected robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several people hurt by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
