An additional two individuals are now in custody related to a robbery at London's Heathrow Airport where over twenty individuals were injured by a substance believed to be an irritant spray, according to police.
A 24-year-old man, was arrested in the Lambeth area on suspicion of robbery and assault and a 23-year-old woman was detained for suspected conspiring to commit a robbery. Both individuals remain in custody, the force said.
These detentions follow an investigation into an assault at the multi-storey car park at Terminal 3 on Sunday. Prior to the attack, two women had stolen from them their luggage after getting out of a car park lift.
A toddler aged three was among the injured 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 on suspicion of theft and assault near the scene. He has since been released pending further inquiries as the investigation proceeds.
Police were called at about 8:10 in the morning GMT following reports of a number of people injured by an irritating chemical believed to be an irritant spray.
The attack - an event that police said was a standalone incident and not being treated as an act of terror - resulted in train delays and the temporary shutdown of the Central Terminal Area tunnel and the Terminal 3 car park briefly.
