An additional two individuals have been arrested in connection with a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested 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 assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for medical care and have since been released.
Officers arrested a man in his thirties on suspicion of theft and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT following reports of several people injured by an irritating chemical believed to be pepper spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
