An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
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. They both are still being held, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured during the incident. Five people went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties for suspected theft and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
