An additional two individuals are now in custody related to a robbery at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be an irritant spray, as stated by police.
A man, 24, was arrested in Lambeth on suspicion of theft and assault and a 23-year-old woman was detained on suspicion of 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, two women were robbed of their luggage upon exiting a car park lift.
A toddler aged three was among the those hurt during the incident. A total of five individuals went to hospital for medical care and have since been released.
Officers detained a 31-year-old man for suspected theft and assault close to the scene. He has since been released under investigation while inquiries continue.
Authorities were alerted at about 08:10 GMT following reports of several individuals injured by a noxious substance thought to be an irritant spray.
The assault - an event that police said was a standalone incident and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the main airport tunnel and the T3 car park briefly.
