An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been discharged.
Officers detained a man in his thirties on suspicion of theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people hurt by a noxious substance thought to be pepper spray.
The attack - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
