Two more people are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for medical care and were later discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
