Two more people are now in custody in connection with a robbery at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of 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 discharged.
Police arrested a man in his thirties for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be an irritant spray.
The attack - an event that police said was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
