An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. Five people went to hospital for treatment and were later discharged.
Officers arrested a 31-year-old man for suspected robbery and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
