An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth for suspected theft and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the injured during the incident. Five people went to hospital for treatment and have since been discharged.
Officers detained a 31-year-old man for suspected theft and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The assault - an event that authorities stated was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
