Two more people are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
The arrests come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Prior to the attack, two women were robbed of their suitcases upon exiting a parking garage elevator.
A toddler aged three was one of the those hurt in the event. Five people went to hospital for treatment and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding several people hurt by an irritating chemical thought to be pepper spray.
The assault - which authorities stated was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
