An additional two individuals are now in custody related to a robbery at Heathrow Airport in which over twenty individuals were injured by what is thought to be an irritant spray, according to police.
A man, 24, was arrested in Lambeth on suspicion of robbery and assault and a woman, 23 was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow an investigation into an attack at the multi-level parking garage at Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals went to hospital for treatment and were later released.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released under investigation 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 authorities stated was isolated and not considered an act of terror - caused delays to rail services and the temporary shutdown of the main airport tunnel and the Terminal 3 parking facility briefly.
