An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after a probe into an attack at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be an irritant spray.
The assault - which police said was isolated and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the T3 car park for a short time.
