An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Police arrested a man in his thirties for suspected robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
