Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Police arrested a man in his thirties for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical thought to be an irritant spray.
The assault - which police said was isolated and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
