An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A man, 24, was taken into custody in Lambeth on suspicion of theft and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, the force said.
The arrests follow an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Officers detained a man in his thirties for suspected robbery and assault near the location. He has since been released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
