Two more people are now in custody in connection with a theft at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was among the injured during the incident. Five people went to hospital for treatment and were later discharged.
Officers detained a man in his thirties for suspected theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
