An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for treatment and were later released.
Police detained a man in his thirties for suspected theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of several people injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
