An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries 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 arrested on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. A total of five individuals went to hospital for medical care and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of a number of individuals hurt by a noxious substance thought to be pepper 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 Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
