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 law enforcement.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the injured in the event. Five people went to hospital for medical care and have since been discharged.
Police detained a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of several people hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
