An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained 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-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for medical care and have since been discharged.
Police detained a man in his thirties for suspected robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals injured by a noxious substance believed to be pepper spray.
The attack - an event that police said was isolated and not considered terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
