Two more people are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
