An additional two individuals have been arrested in connection with a theft at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people went to hospital for treatment and were later discharged.
Officers arrested a man in his thirties on suspicion of robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was a standalone incident and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
