Two more people are now in custody related to a robbery at Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a 31-year-old man for suspected theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of a number of individuals injured by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
