Two more people are now in custody related to a theft at Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. Five people were taken to the hospital for treatment and were later released.
Police arrested a man in his thirties for suspected robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
