Two more people have been arrested related to a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, according to police.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for medical care and have since been discharged.
Police arrested a man in his thirties for suspected robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals injured by a noxious substance believed to be an irritant spray.
The assault - an event that police said was isolated and not considered an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
