Two more people have been arrested related to a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, authorities confirmed.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people went to hospital for treatment and have since been discharged.
Police arrested a 31-year-old man for suspected theft and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
