Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for medical care and have since been released.
Police arrested a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at about 08:10 GMT following reports of several people hurt by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - caused delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
