Two more people are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by what is thought 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 on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Officers arrested a man in his thirties for suspected theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
