Two more people have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT following reports of several individuals hurt by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was isolated and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
