An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was one of the injured during the incident. Five people were taken to the hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
