Two more people have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be pepper spray.
The attack - an event that police said was isolated and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
