An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. Five people were taken to the hospital for medical care and were later discharged.
Officers arrested a 31-year-old man on suspicion of robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of several people injured by an irritating chemical thought to be pepper spray.
The assault - which police said was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
