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 an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt in the event. A total of five individuals went to hospital for medical care and have since been discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT following reports of several individuals hurt by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
