An additional two individuals 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, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of theft and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
The arrests follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the attack, 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 injured during the incident. Five people went to hospital for medical care and have since been discharged.
Officers arrested a man in his thirties on suspicion of robbery and assault near 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 people injured by a noxious substance thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility for a short time.
