Two more people have been arrested related to a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault near the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
