Two more people are now in custody related to a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by police.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. Five people went to hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were called at about 08:10 GMT following reports of a number of 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 an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
