An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and have since been released.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
