Two more people have been arrested related to a robbery at Heathrow Airport where 21 people sustained injuries by what is thought to be pepper spray, as stated by 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 arrested on suspicion of conspiring to commit a robbery. They both are still being held, the force said.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the incident, a pair of female travelers 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. A total of five individuals went to hospital for treatment and have since been discharged.
Police arrested a man in his thirties on suspicion of robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by a noxious substance believed to be an irritant spray.
The assault - which police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 parking facility briefly.
