Two more people are now in custody in connection with a theft at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers were robbed of 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 detained a 31-year-old man on suspicion of theft and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several individuals injured by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park briefly.
