Two more people have been arrested in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an assault 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 suitcases upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and were later discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people injured by a noxious substance thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
