An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, 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. Both individuals are still being held, authorities confirmed.
The arrests come after a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals went to hospital for treatment and have since been released.
Officers detained a 31-year-old man for suspected robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at about 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance believed to be an irritant spray.
The assault - an event that police said was isolated 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.
