An additional two individuals have been arrested related to a theft at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. They both remain in custody, authorities confirmed.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was one of the injured during the incident. Five people were taken to the hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected theft and assault close to the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at about 08:10 GMT after reports came in regarding a number of individuals hurt by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
