An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals went to hospital for medical care and have since been released.
Police detained a 31-year-old man for suspected robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of several people injured by a noxious substance believed to be pepper spray.
The assault - which police said was isolated and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
