Two more people have been arrested related to a robbery at London's Heathrow Airport in which 21 people were injured by a substance believed to be pepper 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 detained on suspicion of conspiring to commit a robbery. They both remain in custody, the force said.
These detentions come after a probe into an assault at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Prior to the incident, a pair of female travelers had stolen from them their luggage after getting out of a parking garage elevator.
A three-year-old girl was among the those hurt during the incident. A total of five individuals were taken to the hospital for medical care and have since been released.
Officers detained a 31-year-old man on suspicion of robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Authorities were called at approximately 8:10 in the morning GMT following reports of several people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as terrorism - caused delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
