An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which 21 people sustained injuries by what is thought to be pepper spray, as stated by police.
A man, 24, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
These detentions follow a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, two women were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people went to hospital for treatment and have since been discharged.
Police detained a 31-year-old man for suspected robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
