Two more people have been arrested in connection with a robbery at Heathrow Airport where 21 people were injured by a substance believed to be pepper spray, according to law enforcement.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. They both are still being held, the force said.
The arrests follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the attack, two women had stolen from them their suitcases after getting out of a car park lift.
A toddler aged three was among the injured in the event. Five people were taken to the hospital for medical care and were later released.
Police arrested a man in his thirties on suspicion of theft and assault close to the location. He has since been released pending further inquiries as the investigation proceeds.
Police were called at approximately 08:10 GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be an irritant spray.
The assault - which police said was a standalone incident and not considered an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 car park briefly.
