Two more people have been arrested related to a robbery at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, according to police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women had stolen from them their suitcases 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 medical care and were later released.
Police detained a man in his thirties for suspected robbery and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT following reports of a number of individuals hurt by an irritating chemical believed to be pepper spray.
The assault - an event that police said was isolated and not considered an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
