An additional two individuals are now in custody 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 law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for treatment and were later released.
Officers arrested a man in his thirties on suspicion of theft and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT following reports of several people hurt by an irritating chemical thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
