An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the incident, two women had stolen from them their suitcases upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. Five people were taken to the hospital for medical care and have since been discharged.
Officers detained a man in his thirties for suspected theft and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at approximately 08:10 GMT after reports came in regarding several individuals injured by an irritating chemical thought to be an irritant spray.
The attack - which authorities stated was isolated and not considered an act of terror - caused train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
