An additional two individuals are now in custody related to a robbery at Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, 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 remain in custody, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals went to hospital for treatment and were later released.
Officers arrested a man in his thirties on suspicion of robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
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 an irritant spray.
The assault - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
