Two more people are now in custody related to a robbery at Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, 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 incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for medical care and have since been released.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
