Two more people have been arrested in connection with a robbery at London's Heathrow Airport where 21 people were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 on Sunday. Before the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and were later released.
Police detained a 31-year-old man for suspected theft and assault near the location. He has since been released pending further inquiries as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
