An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an assault 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 three-year-old girl was one of the injured during the incident. Five people went to hospital for treatment and were later discharged.
Police arrested a man in his thirties for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of several people hurt by a noxious substance thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
