An additional two individuals are now in custody related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Police detained a man in his thirties on suspicion of theft and assault near the location. He has since been released under investigation while inquiries continue.
Police 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 assault - which police said was isolated 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.
