Two more people have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and were later released.
Officers detained a 31-year-old man for suspected robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
