An additional two individuals are now in custody in connection with a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth for suspected robbery and assault and a woman, 23 was detained on suspicion of conspiracy to commit robbery. They both are still being held, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 on Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage upon exiting a parking garage elevator.
A toddler aged three was among the those hurt during the incident. Five people went to hospital for medical care and have since been released.
Police arrested a man in his thirties for suspected theft and assault close to the scene. He has since been released under investigation as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals injured by an irritating chemical believed to be pepper spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the T3 parking facility briefly.
