An additional two individuals have been arrested in connection with a theft at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, according to police.
A man, 24, was arrested in the Lambeth area on suspicion of robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both remain in custody, the force said.
These detentions follow an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Officers arrested a man in his thirties for suspected robbery and assault close to the scene. He has since been released under investigation while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was isolated and not being treated as terrorism - caused train delays and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
