An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for treatment and have since been released.
Officers detained a man in his thirties for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of a number of individuals injured by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
