An additional two individuals are now in custody related to a theft at Heathrow Airport in which over twenty individuals sustained injuries by what is thought to be pepper spray, according to police.
A man, 24, was arrested in Lambeth for suspected robbery and assault and a 23-year-old woman was detained on suspicion of conspiracy to commit robbery. Both individuals remain in custody, the force said.
The arrests come after an investigation into an attack at the multi-storey car park at Terminal 3 on Sunday. Before the incident, a pair of female travelers had stolen from them their suitcases after getting out of a parking garage elevator.
A three-year-old girl was among the injured in the event. Five people were taken to the hospital for treatment and have since been discharged.
Officers detained a 31-year-old man for suspected robbery and assault close to the scene. He has since been released pending further inquiries while inquiries continue.
Police were called at approximately 08:10 GMT after reports came in regarding several individuals hurt by a noxious substance thought to be pepper spray.
The attack - which authorities stated was isolated and not considered terrorism - resulted in delays to rail services and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
