An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. Five people went to hospital for medical care and were later released.
Police detained a 31-year-old man on suspicion of theft and assault near the location. He has since been released under investigation while inquiries continue.
Police were called at about 08:10 GMT following reports of several individuals hurt by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
