An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers arrested a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of people hurt by an irritating chemical thought to be pepper spray.
The assault - which police said was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
