An additional two individuals have been arrested related to a robbery at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the injured during the incident. Five people went to hospital for treatment and were later released.
Officers detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
