An additional two individuals have been arrested related to a theft at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth 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, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of several individuals hurt by a noxious substance believed to be pepper spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
