An additional two individuals have been arrested related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later discharged.
Police detained a 31-year-old man for suspected robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park for a short time.
