An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of 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-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Police arrested a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
