An additional two individuals have been arrested related to a robbery at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt in the event. Five people went to hospital for treatment and have since been discharged.
Officers detained a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 8:10 in the morning GMT following reports of a number of people injured by a noxious substance thought to be an irritant spray.
The attack - an event that police said was a standalone incident and not considered an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
