An additional two individuals have been arrested related to a theft at Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery 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.
These detentions come after an investigation into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Before the incident, two women had stolen from them 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 released.
Officers detained a 31-year-old man for suspected robbery and assault near the scene. He was subsequently released pending further inquiries while inquiries continue.
Authorities were alerted at approximately 08:10 GMT following reports of a number of individuals hurt by an irritating chemical believed to be an irritant spray.
The assault - which police said was isolated and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
