An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for treatment and have since been discharged.
Officers detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - an event that police said was a standalone incident 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 T3 car park for a short time.
