An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, 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 in the event. A total of five individuals were taken to the hospital for treatment and were later discharged.
Officers arrested a 31-year-old man for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility briefly.
