An additional two individuals have been arrested in connection with a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance thought to be an irritant 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 main airport tunnel and the Terminal 3 car park for a short time.
