An additional two individuals are now in custody related to a theft at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before 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 in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Police detained a man in his thirties for suspected robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
