Two more people are now in custody related to a robbery at Heathrow Airport where 21 people 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 robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Police detained a 31-year-old man for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
