Two more people are now in custody in connection with a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a car park lift.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Police 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.
Police were called at about 08:10 GMT following reports of a number of people hurt by a noxious substance believed to be pepper spray.
The attack - an event that police said was isolated 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 T3 parking facility briefly.
