An additional two individuals have been arrested related to a theft at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties for suspected theft and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals injured by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
