Two more people have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, according to law enforcement.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police detained a man in his thirties for suspected theft and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding several people hurt by a noxious substance believed to be an irritant spray.
The attack - which police said was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
