Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, 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. They both are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for treatment and have since been released.
Officers arrested a man in his thirties on suspicion of robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT following reports of a number of individuals injured by a noxious substance thought to be an irritant spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
