Two more people have been arrested in connection with a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for medical care and were later released.
Police detained a man in his thirties for suspected theft and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of several people hurt by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
