An additional two individuals are now in custody in connection with a robbery at London's Heathrow Airport in which over twenty individuals sustained injuries by a substance believed to be an irritant spray, as stated by police.
A man, 24, was arrested in the Lambeth area for suspected robbery and assault and a 23-year-old woman was detained for suspected conspiracy to commit robbery. Both individuals remain in custody, authorities confirmed.
These detentions follow a probe into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before 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 those hurt in the event. A total of five individuals were taken to the hospital for treatment and have since been released.
Officers detained a man in his thirties on suspicion of robbery and assault close to the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at about 08:10 GMT following reports of several people hurt by an irritating chemical believed to be pepper spray.
The assault - which authorities stated was a standalone incident and not being treated as terrorism - caused train delays and the partial closure of the Central Terminal Area tunnel and the T3 car park briefly.
