Two more people have been arrested in connection with a theft at London's Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, according to 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. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage upon exiting a car park lift.
A three-year-old girl was among the those hurt during the incident. A total of five individuals went to hospital for treatment and were later released.
Police detained a 31-year-old man for suspected theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT after reports came in regarding several individuals hurt by a noxious substance believed to be pepper spray.
The attack - which police said 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 T3 car park for a short time.
