An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for medical care and have since been discharged.
Officers arrested a man in his thirties on suspicion of theft and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT following reports of a number of people hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was isolated and not being treated as terrorism - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
