Two more people are now in custody in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
The arrests come after a probe into an assault at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their suitcases upon exiting a car park lift.
A three-year-old girl was among the injured during the incident. Five people went to hospital for treatment and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT following reports of several individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
