Two more people have been arrested related to a robbery 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 Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiring to commit a robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a car park lift.
A three-year-old girl was among the those hurt during the incident. Five people were taken to the hospital for treatment and were later discharged.
Police arrested a man in his thirties for suspected robbery and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Police were alerted at about 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical thought to be an irritant spray.
The assault - which authorities stated was isolated and not considered terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
