Two more people have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured in the event. Five people went to hospital for medical care and were later discharged.
Officers arrested a man in his thirties for suspected robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical thought to be pepper spray.
The attack - an event that 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 parking facility briefly.
