An additional two individuals have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by police.
A man, 24, was taken into custody in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for treatment and have since been released.
Officers detained a man in his thirties on suspicion of robbery and assault near the location. He was subsequently released under investigation as the investigation proceeds.
Police were called at about 08:10 GMT following reports of several people hurt by an irritating chemical thought to be pepper spray.
The assault - an event that police said was isolated and not being treated as terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
