An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. Five people were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
