Two more people have been arrested related to a robbery at Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on 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 were taken to the hospital for medical care and have since been discharged.
Police detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of several individuals injured by a noxious substance thought to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
