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 what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not considered terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
