Two more people are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman 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-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals hurt by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
