Two more people have been arrested related to a theft at London's Heathrow Airport where 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 woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and were later released.
Police detained a man in his thirties for suspected robbery and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of several people injured by a noxious substance believed to be an irritant spray.
The assault - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
