Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. Five people went to hospital for treatment and have since been discharged.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT following reports of several people injured by a noxious substance thought to be pepper spray.
The attack - which police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 car park for a short time.
