An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on 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 those hurt in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Police arrested a man in his thirties for suspected theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of a number of people injured by a noxious substance believed to be pepper spray.
The assault - an event that police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
