Two more people are now in custody related to a theft at Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests come after an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the those hurt during the incident. A total of five individuals went to hospital for medical care and were later discharged.
Officers detained a 31-year-old man for suspected theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility briefly.
