Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the injured during the incident. Five people were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of people injured by an irritating chemical believed to be an irritant spray.
The assault - which police said was isolated and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 car park briefly.
