Two more people have been arrested related to a theft at Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released under investigation while inquiries continue.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
