Two more people are now in custody in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for medical care and were later discharged.
Police detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several individuals hurt by a noxious substance thought to be pepper spray.
The attack - 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 car park for a short time.
