An additional two individuals are now in custody in connection with a robbery at London's 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 theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people went to hospital for medical care and have since been released.
Officers detained a man in his thirties on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of a number of people injured by a noxious substance believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not considered an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
