An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport where 21 people sustained injuries by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in the Lambeth area for suspected theft and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at 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 injured in the event. A total of five individuals went to hospital for treatment and have since been released.
Officers arrested a 31-year-old man on suspicion of robbery and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The assault - an event that police said was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
