An additional two individuals have been arrested related to a theft at Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A man, 24, was taken into custody in Lambeth for suspected robbery and assault and a 23-year-old woman was arrested on suspicion of conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
The arrests follow a probe into an attack at the multi-storey car park at Terminal 3 this past Sunday. Prior to the incident, two women were robbed of their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the injured during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Police detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries while inquiries continue.
Police were called at about 08:10 GMT following reports of a number of individuals injured by an irritating chemical believed to be pepper spray.
The assault - an event that authorities stated was isolated and not considered terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
