An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals sustained injuries by what is thought to be an irritant spray, according to police.
A 24-year-old man, was arrested in Lambeth for suspected theft and assault and a woman, 23 was detained for suspected conspiracy to commit robbery. They both are still being held, the force said.
These detentions come after a probe into an attack at the multi-storey car park at Heathrow's Terminal 3 this past Sunday. Before the incident, a pair of female travelers were robbed of their luggage after getting out of a car park lift.
A toddler aged three was among the injured in the event. A total of five individuals were taken to the hospital for medical care and were later released.
Police detained a 31-year-old man for suspected theft and assault near the location. He was subsequently released pending further inquiries as the investigation proceeds.
Authorities were called at approximately 8:10 in the morning GMT after reports came in regarding a number of people hurt by an irritating chemical believed to be an irritant spray.
The assault - which authorities stated was isolated and not being treated as an act of terror - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 parking facility for a short time.
