An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before 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. Five people went to hospital for medical care and were later discharged.
Officers detained a man in his thirties for suspected robbery and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of several people injured by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
