An additional two individuals are now in custody related to a robbery at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions come after a probe 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 suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for medical care and have since been released.
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.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not considered 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.
