Two more people have been arrested in connection with a robbery at London's Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an assault at the multi-storey car park 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 injured during the incident. A total of five individuals were taken to the hospital for treatment and were later released.
Police detained a man in his thirties for suspected theft and assault near the scene. He has since been released under investigation while inquiries continue.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The assault - an event that police said was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
