An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, as stated by law enforcement.
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 are still being held, the force said.
These detentions follow an investigation 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 had stolen from them their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt in the event. Five people went to hospital for medical care and have since been discharged.
Officers detained a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be pepper spray.
The attack - which police said was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
