Two more people are now in custody in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. A total of five individuals went to hospital for medical care and have since been released.
Police detained a man in his thirties for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of a number of people injured by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
