Two more people have been arrested in connection with a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later discharged.
Police arrested a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated 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 T3 parking facility briefly.
