Two more people have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. A total of five individuals 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 while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
