An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for treatment and were later released.
Police arrested a man in his thirties for suspected theft and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
