Two more people have been arrested related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was arrested for suspected conspiring to commit a robbery. They both remain in custody, the force said.
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 luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the injured in the event. Five people went to hospital for treatment and were later discharged.
Police detained a man in his thirties for suspected theft and assault near the location. He has since been released under investigation 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 attack - which authorities stated was isolated and not considered 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.
