Two more people have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a 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 luggage after getting out of a car park lift.
A toddler aged three was among the injured during the incident. A total of five individuals went to hospital for treatment and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT following reports of a number of people injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
