Two more people are now in custody related to a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
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 attack, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people went to hospital for medical care and were later released.
Police arrested a man in his thirties on suspicion of theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance thought to be pepper spray.
The assault - which police said was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
