Two more people have been arrested related to a theft at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper spray, as stated by police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained for suspected conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for treatment and have since been discharged.
Officers arrested a man in his thirties for suspected robbery and assault near the location. He has since been released under investigation while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding several people hurt by a noxious substance believed to be pepper spray.
The assault - an event that police said was a standalone incident and not considered terrorism - caused delays to rail services and the partial closure of the main airport tunnel and the T3 parking facility briefly.
