Two more people are now in custody related to a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for treatment and were later released.
Police detained a 31-year-old man on suspicion of theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
