Two more people are now in custody related to a theft at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past 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 one of the injured in the event. Five people were taken to the 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 as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be an irritant spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
