Two more people have been arrested related to a theft at London's Heathrow Airport where 21 people were injured by what is thought to be pepper spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
These detentions come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called 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 a standalone incident and not being treated as terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
