Two more people are now in custody related to a theft at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals went to hospital for medical care and were later released.
Officers arrested a 31-year-old man for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding several people injured by an irritating chemical thought to be pepper spray.
The attack - which authorities stated was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
