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 24-year-old man, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. Five people were taken to the hospital for treatment and have since been discharged.
Officers detained a 31-year-old man on suspicion of theft and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of a number of people hurt by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
