Two more people have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for treatment and have since been released.
Officers detained a 31-year-old man on suspicion of robbery 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 a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
