An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of theft and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. They both remain in custody, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt during the incident. Five people were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties on suspicion of theft and assault close to the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were alerted at about 8:10 in the morning GMT following reports of a number of people injured by a noxious substance believed to be an irritant spray.
The attack - which authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
