An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport in which 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A man, 24, was taken into custody in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before 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 released.
Officers detained a man in his thirties for suspected robbery and assault close to the scene. He was subsequently released under investigation as the investigation proceeds.
Authorities were alerted at about 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance thought to be pepper spray.
The assault - which police said was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
