An additional two individuals are now in custody related to a robbery at Heathrow Airport where 21 people were injured by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals went to hospital for treatment and have since been released.
Police arrested a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of a number of people hurt by a noxious substance thought to be an irritant spray.
The assault - which authorities stated was isolated and not considered an act of terror - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
