Two more people are now in custody related to a robbery at Heathrow Airport in which 21 people were injured by what is thought to be pepper spray, as stated by police.
A 24-year-old man, was arrested in Lambeth for suspected robbery and assault and a woman, 23 was arrested on suspicion of conspiring to commit a robbery. They both are still being held, authorities confirmed.
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, two women were robbed of their luggage upon exiting 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 treatment and were later discharged.
Officers arrested a 31-year-old man for suspected theft and assault close to the scene. He was subsequently released under investigation while inquiries continue.
Authorities were alerted at approximately 8:10 in the morning GMT after reports came in regarding a number of people injured by an irritating chemical thought to be an irritant spray.
The attack - which police said was isolated and not being treated as an act of terror - resulted in delays to rail services and the partial closure of the Central Terminal Area tunnel and the T3 parking facility for a short time.
