Two more people are now in custody related to a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, 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 are still being held, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Police arrested a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
