An additional two individuals have been arrested in connection with a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, 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. Five people were taken to the hospital for medical care and have since been released.
Police detained a 31-year-old man on suspicion of robbery and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals injured by a noxious substance thought to be an irritant spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility for a short time.
