An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt in the event. A total of five individuals went to hospital for treatment and have since been discharged.
Officers arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Authorities were alerted at about 8:10 in the morning GMT following reports of a number of individuals injured by an irritating chemical thought to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
