An additional two individuals are now in custody related to a theft at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, as stated by law enforcement.
A 24-year-old man, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiring to commit a robbery. Both individuals are still being held, authorities confirmed.
These detentions follow a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was one of the those hurt in the event. A total of five individuals were taken to the hospital for medical care and have since been discharged.
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 following reports of a number of individuals injured by a noxious substance thought to be an irritant spray.
The attack - an event that authorities stated was a standalone incident and not considered an act of terror - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
