Two more people have been arrested related to a robbery at Heathrow Airport in which 21 people sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was taken into custody in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. They both are still being held, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was one of the injured in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Police detained a 31-year-old man for suspected robbery and assault near the location. He has since been released under investigation as the investigation proceeds.
Authorities were alerted at approximately 08:10 GMT following reports of several 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 terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
