An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals were injured by what is thought to be pepper spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. Both individuals are still being held, the force said.
The arrests come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was one of the injured in the event. A total of five individuals went to hospital for treatment and were later discharged.
Officers arrested a man in his thirties for suspected theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be an irritant spray.
The attack - which authorities stated was a standalone incident and not being treated as an act of terror - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 car park for a short time.
