An additional two individuals have been arrested related to a theft 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 24-year-old man, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women were robbed of their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the location. He has since been released under investigation as the investigation proceeds.
Authorities were called at about 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical thought to be pepper spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
