Two more people are now in custody in connection with a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Prior to the incident, two women were robbed of their suitcases after getting out of a parking garage elevator.
A toddler aged three was among the injured in the event. Five people went to hospital for treatment and have since been released.
Police arrested a 31-year-old man for suspected robbery and assault near the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 08:10 GMT after reports came in regarding a number of people injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park for a short time.
