Two more people have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for medical care and have since been released.
Officers arrested a 31-year-old man for suspected robbery and assault near the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals injured by a noxious substance thought 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 Terminal 3 parking facility for a short time.
