An additional two individuals are now in custody related to a robbery at London's Heathrow Airport in which 21 people were injured 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 for suspected conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Police detained a man in his thirties for suspected theft and assault close to the location. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT after reports came in regarding several people hurt by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was a standalone incident and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
