Two more people have been arrested related to a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought 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 woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, authorities confirmed.
The arrests follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women had stolen from them their suitcases upon exiting a car park lift.
A toddler aged three was one of the injured in the event. Five people were taken to the hospital for treatment and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault near the scene. He was subsequently released under investigation while inquiries continue.
Police were called at about 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not considered terrorism - resulted in train delays and the partial closure of the main airport tunnel and the Terminal 3 parking facility briefly.
