Two more people are now in custody in connection with a theft at 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 Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, the force said.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers 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 were taken to the hospital for treatment and were later discharged.
Police arrested a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT following reports of a number of people hurt by a noxious substance thought to be pepper spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - resulted in train delays and the partial closure of the main airport tunnel and the T3 parking facility for a short time.
