An additional two individuals have been arrested related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be pepper spray, according to police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. Both individuals are still being held, the force said.
These detentions come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Prior to 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. A total of five individuals were taken to the hospital for treatment and were later discharged.
Officers arrested a 31-year-old man 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 several individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - an event that police said was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park briefly.
