An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers detained a man in his thirties on suspicion of theft and assault near the location. He has since been released under investigation while inquiries continue.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
