Two more people have been arrested related to a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected theft 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 a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Officers detained a 31-year-old man for suspected robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT following reports of a number of individuals hurt by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not considered terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 car park briefly.
