An additional two individuals are now in custody related to a theft at Heathrow Airport where 21 people were injured by what is thought to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests come after a probe into an attack at the multi-level parking garage at Heathrow's Terminal 3 on Sunday. Before the attack, two women were robbed of their luggage after getting out of a car park lift.
A three-year-old girl was one of the those hurt in the event. Five people were taken to the hospital for treatment and were later discharged.
Police detained a man in his thirties on suspicion of robbery and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were alerted at about 08:10 GMT after reports came in regarding several people hurt by an irritating chemical believed to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered terrorism - caused delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the T3 parking facility for a short time.
