An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people went to hospital for medical care and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of several individuals hurt by a noxious substance believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
