Two more people are now in custody related to a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, according to law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. 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 a number of individuals hurt by a noxious substance believed to be an irritant spray.
The assault - an event that authorities stated was isolated and not being treated as an act of terror - caused train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility for a short time.
