An additional two individuals are now in custody in connection with a robbery at Heathrow Airport where over twenty individuals sustained injuries by a substance believed to be pepper 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. Both individuals are still being held, the force said.
The arrests follow an investigation into an assault at the multi-level parking garage at Terminal 3 this past Sunday. Before the attack, two women were robbed of their luggage upon exiting a car park lift.
A three-year-old girl was one of the injured in the event. Five people were taken to the hospital for treatment and were later discharged.
Officers detained a 31-year-old man on suspicion of theft and assault close to the location. He was subsequently released under investigation as the investigation proceeds.
Police were alerted at approximately 08:10 GMT after reports came in regarding a number of people injured by a noxious substance thought to be pepper spray.
The assault - an event that police said was isolated and not being treated as terrorism - resulted in train delays and the partial closure of the Central Terminal Area tunnel and the Terminal 3 car park for a short time.
