Two more people are now in custody related to a robbery at Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for treatment and have since been released.
Officers arrested a 31-year-old man on suspicion of theft and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
