Two more people are now in custody in connection with a robbery at Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions come after an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people went to hospital for medical care and have since been released.
Officers detained a man in his thirties for suspected robbery and assault close to the location. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding several individuals hurt by an irritating chemical believed to be pepper spray.
The assault - which police said was isolated and not considered terrorism - resulted in delays to rail services and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
