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 an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the those hurt in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers detained a man in his thirties for suspected theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were called at about 08:10 GMT following reports of a number of people injured by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
