Two more people are now in custody in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
These detentions come after 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 had stolen from them their suitcases upon exiting a car park lift.
A three-year-old girl was one of the those hurt during the incident. Five people went to hospital for treatment and have since been released.
Police detained a 31-year-old man for suspected theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical thought to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
