An additional two individuals have been arrested related to a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a man in his thirties on suspicion of theft and assault near the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding several people injured by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not considered terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
