An additional two individuals have been arrested related to a robbery at Heathrow Airport in which 21 people sustained injuries by a substance believed to be an irritant spray, according to law enforcement.
A 24-year-old man, was taken into custody in Lambeth on suspicion of robbery and assault and a 23-year-old woman was arrested for suspected conspiracy to commit robbery. They both remain in custody, authorities confirmed.
These detentions come after a probe into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the attack, a pair of female travelers had stolen from them their luggage after getting out of a car park lift.
A three-year-old girl was among the injured in the event. A total of five individuals were taken to the hospital for medical care and have since been released.
Police arrested a 31-year-old man for suspected robbery and assault close to the location. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance believed to be an irritant spray.
The assault - an event that police said was isolated and not being treated as terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
