An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for medical care and have since been discharged.
Police detained a 31-year-old man for suspected robbery 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 several individuals injured by an irritating chemical thought to be pepper spray.
The assault - which police said was isolated and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
