An additional two individuals have been arrested related to a robbery at London's Heathrow Airport in which 21 people sustained injuries by a substance believed to be pepper spray, as stated by police.
A man, 24, was taken into custody 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, authorities confirmed.
The arrests follow an investigation into an assault at the multi-storey car park at Terminal 3 this past Sunday. Before the incident, two women had stolen from them their luggage after getting out of a parking garage elevator.
A toddler aged three was one of the injured in the event. 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 for suspected robbery and assault near the scene. He was subsequently released pending further inquiries as the investigation proceeds.
Police were called at approximately 8:10 in the morning GMT after reports came in regarding a number of individuals hurt by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not considered terrorism - caused train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
