Two more people have been arrested in connection with a robbery at Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both remain in custody, the force said.
The arrests follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for medical care and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault close to the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
