An additional two individuals are now in custody in connection with a theft at London's Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiracy to commit robbery. They both are still being held, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and were later released.
Officers arrested a man in his thirties for suspected theft 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 after reports came in regarding several people injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park for a short time.
