Two more people have been arrested in connection with a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT following reports of several people hurt by a noxious substance believed to be pepper spray.
The assault - which police said was a standalone incident and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
