An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected 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 on Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for treatment and have since been released.
Officers arrested a 31-year-old man on suspicion of theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Police were alerted at approximately 8:10 in the morning GMT after reports came in regarding several people injured by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was isolated and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility briefly.
