An additional two individuals have been arrested related to a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 this past 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 among the those hurt during the incident. Five people were taken to the hospital for medical care and were later discharged.
Police arrested a man in his thirties for suspected theft and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding several people injured by a noxious substance believed to be pepper spray.
The attack - an event that police said was isolated and not considered an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
