Two more people are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals went to hospital for treatment and were later released.
Police detained a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 8:10 in the morning GMT following reports of a number of people injured by a noxious substance believed to be pepper spray.
The attack - which police said was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
